HOW TO USE THE LISTINGS

General-use Micro-Measurements strain gages are listed in groups according to grid geometry:

ADVANCED SENSORS GAGES

Customers whose application requires gages for the manufacture of

precision commercial transducers are strongly encouraged to contact our

Applications Engineering Department. They can provide assistance in the

selection of the proper Advanced Sensor for your particular application.

CUSTOM GAGES

Micro-Measurements maintains the most extensive variety of catalog

strain gages available today. Whether for stress analysis, transducer

manufacturing, or special-purpose applications, we have not only a wide

selection, but also a large and varied inventory that is readily available for

immediate delivery.
However, many of our customers have applications requiring gages that

are manufactured to their individual specifications. While we believe our

wide variety of standard catalog gages will satisfy most requirements, we

recognize the need for custom products and are committed to serving it well.
To request a quotation for a custom gage, please contact our Applications

Selection Criteria

Stress Analysis Strain Gages

GAGE SELECTION

Many factors, such as test duration, strain range required,

and operating temperature, must be considered in

selecting the best strain gage/adhesive combination for a

given test profile. These factors and others are addressed

in Tech Note TN-505, “Strain Gage Selection—Criteria,

Procedures, Recommendations.”

SELF-TEMPERATURE

COMPENSATION (S-T-C)

All gages with XX as the second code group in the gage

designation are self-temperature-compensated for use

on structural materials with specific thermal expansion

coefficients. The table below lists S-T-C numbers and

test specimen materials to which gages are thermally

matched.
When ordering, replace the XX code group with the

desired S-T-C number, which is the approximate thermal

expansion coefficient of the structural material in ppm/°F.

The Gage Designation System lists the available S-T-C

numbers for specific grid alloys. The 06 and 13 values,

available in A and K alloys, are most common and more

likely to be in stock. When not otherwise specified, the 06

compensation is shipped.

GAGE RESISTANCE

Micro-Measurements strain gages are available in various

resistance values that range from 30 to 5000 ohms.
Strain gages with resistances of 120 and 350 ohms are

commonly used in experimental stress analysis testing.

For the majority of applications, 120-ohm gages are

usually suitable; 350-ohm gages would be preferred to

reduce heat generation (for the same applied voltage

across the gage), to decrease leadwire effects, or

to improve signal-to-noise ratios in the gage circuit.

Higher resistance gages are typically used in transducer

applications and on composite materials.

GAGE FACTOR

Gage Factor (GF) is the measure of sensitivity, or

output

produced by a resistance strain gage. Gage factor is

determined through calibration of the specific gage type,

and is the ratio between ΔR/R

and ΔL/L (strain), where

is the initial unstrained resistance of the gage. It is

affected somewhat by pattern size, geometry, S-T-C

number, and temperature. Each gage package is supplied

with the GF as well as its tolerance and temperature

sensitivity. Nominal gage factors for various alloys are:

A = 2.05; K = 2.1; D = 3.2; P = 2.00.

TRANSVERSE SENSITIVITY

All gages are sensitive, to some degree, to strains

transverse to the grid direction. The transverse sensitivity

factor (K

) is given with the engineering data supplied with

all gage types for which the data is relevant.

STRAIN GAGE ADHESIVE SELECTION

When selecting a strain gage, it is most important to

consider the adhesive that will be used to bond the

gage, since the adhesive becomes part of the gage

system and correspondingly affects the performance

of the gage. However, when the interaction of test

characteristics becomes too complex for selecting the

gage/adhesive combination in a straight forward manner,

contact our Applications Engineering Department for

recommendations.

Note 1:

Products with designations and options shown in bold are not RoHS compliant.

The most widely used practical technique for determining

residual stresses is the hole-drilling strain gage method

described in ASTM Standard E837. With this method,

a specially configured strain gage rosette is bonded to

the surface of the test object; and a small, shallow hole

is introduced into the structure, through the center of

the gage, with a precision drilling apparatus. Strains in

the immediate vicinity of the hole are measured, and

the relaxed residual stresses are computed from these

measurements. The general theory of making residual

stress measurements is covered in Micro-Measurements

Tech Note TN-503, “Measurement of Residual Stresses

by the Hole-Drilling Strain Gage Method” and the requisite

hardware is described in Datasheet 11304.

CONSTRUCTION

All gages are constructed of self-temperature-

compensated foil (06 and 13 S-T-C) on a flexible

polyimide carrier, and incorporate a centering target for

use with a precision milling guide. EA-Series (A-Alloy)

gages are available “open-faced” or with solder dots and

encapsulation (Option SE); CEA-Series (A-Alloy) gages

have encapsulated grids, and rugged, copper-coated

solder tabs. Construction of the N2K Series (K-alloy) is

similar to the N2A Series and includes copper pads (DP)

on the solder tabs. The 062UM gage permits installation

adjacent to weldments and intersecting surfaces.

Where magnetic noise is likely to be encountered, the selection of the strain gage grid alloy should be given careful

consideration. If the grid alloy is magnetic, it will be subject to extraneous physical forces in a magnetic field; and,

if magnetoresistive, will undergo spurious resistance changes. Similarly, if the alloy is magnetostrictive, the grid

will tend to change length in the magnetic field. While constantan is comparatively free from magnetic effects over

its normal operating temperature range, specific measurement applications may indicate desirability of a different

sensing grid alloy. Contact our Applications Engineering Department for details.

Intense, time-varying electromagnetic fields with steep

gradients in field strength can cause troublesome noise

in strain gage circuits. In severe magnetic environments,

with low signal levels, the noise amplitude may be

several times larger than the strain signal from the gage.

Micro-Measurements H-Series noninductive strain gages

have been specially designed to minimize noise pickup in

the gage grid due to electromagnetic fields.
H-Series strain gages consist of two identical grids,

with one stacked directly above and insulated from, the

other. The upper and lower grid elements are connected

in series so that current flows in opposite directions

through the two grids. With this arrangement, noise

voltages induced in the grid tend to be self-cancelling.

The counter-current principle employed in H-Series gages

is particularly effective against magnetic field gradients

parallel to the test surface.
H-Series strain gages have been used very successfully

in fusion research applications and similar environments

with flux densities to 50 000 gauss.

CONSTRUCTION

H-Series strain gages are constructed with two 350-ohm

constantan alloy foil grids on a glass-fiber-reinforced

epoxy phenolic carrier. These fully encapsulated gages

include closely spaced, heavy copper terminals for direct

leadwire attachment. H-Series gages are available in

both a single axis and a delta (60°) rosette pattern. The

available S-T-C number is 06.

ADHESIVES

Micro-Measurements M-Bond 600 or AE-15 adhesive

systems are particularly recommended; M-Bond 600

produces the thinnest glueline. Adhesive cure temperature

should not exceed the maximum sensor operating

temperature of +250°F (+120°C).

LEADWIRES

In many cases, the leadwire system itself is the principal

source of magnetic noise induction in the measuring

circuit. Careful attention to details as outlined in

Micro-Measurements Tech Note TN-501, “Noise Control

in Strain Gage Measurements”, is strongly recommended.

Standard Weldable Patterns

Special Use Sensors—Weldable Strain Gages

Micro-Measurements Standard Weldable Strain Gages

and Temperature Sensors are specially designed for spot

welding to structures and components. They are ideal

for applications where test or environmental conditions

preclude clamping and curing an adhesively bonded

gage installation. These gages are equally advantageous

when strain measurements must be made at an elevated

temperature, but the nature of the test object does

not permit the use of an elevated-temperature-curing

adhesive.
Surface preparation requirements are minimal; only an

appropriate solvent cleaning and abrasion of the test part

surface with silicon-carbide paper or a small, hand-held

grinder is needed. Spot welding is accomplished with

a portable stored-energy hand-probe spot welder, such

as the Model 700. Environmental protection is as easily

applied to a welded gage installation as to an adhesively

bonded gage.
Refer to Instruction Bulletin B-131 and MM Strain

Gage Accessories Data Book for further information on

installation and protective coatings. For specifications

about the Model 700 Welding/Soldering Unit, please refer

to the product datasheet.

DESCRIPTION AND PERFORMANCE

General

—All sensors are laboratory-prebonded, with a

high-performance adhesive, to thin [0.005 in (0.13 mm)]

metal carriers. Sensor grids are fully encapsulated for

protection against handling and installation damage.

Standard weldable strain gages are offered in two

series to meet differing performance requirements. Both

series are available in either 06 or 09 self-temperature

compensation. Strain gages with 06 S-T-C have Inconel

carriers, while S-T-C 09 gages and temperature sensors

are mounted on 300-series stainless steel.

CEA-Series Weldable Strain Gage

—Polyimide-

encapsulated constantan foil grid, with large, rugged,

copper-coated tabs. In most cases, the carrier can be

contoured to a radius as small as 1/2 in (13 mm). The CEA

Series is ideal for direct leadwire attachment, before or

after installation.
Strain range is ±5000 μin/in (±5000 μm/m), and normal

operating temperature range is –100° to +200°F (–75°

to +95°C). Short-term maximum temperature is +300°F

(+150°C).

LWK-Series Weldable Strain Gage

—Nickel-chromium

alloy grid, encapsulated in fiberglass-reinforced epoxy

phenolic. The LWK gage is provided with a three-wire lead

system with 10 in (250 mm) of Teflon

-insulated leadwire.

This construction simplifies leadwire temperature

compensation and provides for easy connection of the

lead system to the instrumentation cable. Minimum

installation radius is generally limited to 2 in (50 mm).
Strain range is ±5000 μin/in (±5000 μm/m), and normal

operating temperature range is –320° to +500°F (–195°

to +260°C). Short-term maximum temperature is +550°F

(+290°C).

WWT-Series Temperature Sensor

—High-purity nickel

foil grid encapsulated in fiberglass-reinforced epoxy-

phenolic, and equipped with integral three-tab terminal

to facilitate leadwire attachment. The temperature sensor

is normally installed on a flat surface of the workpiece,

but, in any case, should always be oriented with the

gridlines in the direction of minimum strain to avoid strain-

induced errors (see Micro-Measurements Tech Note

TN-506, “Bondable Resistance Temperature Sensors and

Associated Circuitry”). With an appropriate LST Matching

Network, the temperature response characteristic of the

nickel can be linearized and scaled for direct readout (in

degrees) with any strain indicator.

Teflon is a Registered Trademark of DuPont.

MEASUREMENT CONSIDERATIONS

It is important to note that operating characteristics

of weldable strain gages (gage factor, transverse

sensitivity, and thermal output) are specified for the

basic strain gage itself—without the metal carrier. Thus,

the properties are measured by bonding a conventional

strain gage directly to an appropriate calibration

specimen, following standard methods specified for

all Micro-Measurements strain gages. This procedure

assures the most accurate results, independent of

the variables introduced by welding. In particular, the

user should be aware that the gage factor specified

on the engineering data sheet accompanying the gage

applies only to the basic strain gage, without the shim.

The effective gage factor of the weldable assembly

(after welding to the test member) is commonly 5 to

10% lower than this, due primarily to the stiffness of

the shim. The reduction in gage factor is not subject to

quantitative generalization, because it depends on the

cross-sectional properties of the test specimen, and

on the mode of loading (e.g., bending versus direct

stress). It has been demonstrated, however, that for a

group of like specimens, loaded in the same manner,

the weldable gages exhibit very good repeatability

and uniformity of response. Therefore, when test

requirements dictate greatest accuracy, the weldable

gages should be calibrated on a specimen of the same

material and cross section as the test part, and under

the same mode of loading.

Micro-Measurements Sealed Weldable Strain Gages

are specially designed for spot welding to structures

and components. They are ideally used for applications

where test or environmental conditions preclude clamping

and curing an adhesively bonded gage installation.

These gages are equally advantageous when strain

measurements must be made at elevated temperatures,

but the nature of the test object does not permit the use

of an elevated temperature-curing adhesive. Additionally,

all Micro-Measurements Sealed Weldable Strain Gages

come with a preinstalled protective coating providing

both protection in moist environments and savings in the

time and effort required for making the complete gage

installation.
All sensors are fabricated with EA-Series strain gages,

laboratory-prebonded with a high-performance adhesive

to a thin [0.005 in (0.127 mm)] stainless steel carrier, and

fully encapsulated for protection against moisture. They

have a ±5000 microinch/in strain range, and a normal

operating temperature range of –40°F (–40°C) to +180°F

(+83°C). These gages can be used on surfaces with a

radius of curvature of 3.0 in (76 mm) or greater.
The three leadwire-series of Micro-Measurements Sealed

Weldable Strain Gages have physical constructions

designed for various environmental exposures and

installation constraints.

R-LEADWIRE-SERIES

These gages are designed for long-term out-of-doors use. Primarily used in applications such as railroad and civil

structures, they can be exposed to oil and water splash and short-term submersion in water of shallow [24 in (60 cm)]

depth. The metal carrier is processed to give good first cycle data, excellent fatigue resistance and a high strain range.
Exposure of the vinyl-insulated cable to strong solvents—especially MEK—should be avoided to prevent damage. Long-

term exposure to sub-freezing temperatures requires careful handling to avoid cracking of the vinyl insulation.

T-LEADWIRE-SERIES

This series is designed to withstand exposure to water pressures of up to 500 psi. They can also withstand short-term

(up to 14 days) immersion in crude oil. A flexible stainless steel tube, providing wire routing from the strain gage to a

cable transition, enables fine positioning of the sensor as well as providing strain relief. These sensors are typically used

on larger civil structures, including bridges, dams, and buildings, or for exposures of up to a year in seawater.

High-Temperature Weldable Patterns

Special Use Sensors—Weldable Strain Gages

FEATURES

• High temperature installations using simple attachment

techniques

• Ceramic bonded wire gage performance in a weldable

gage

• Superior performance of bonded gages
• Improved fatigue life for dynamic applications

Micro-Measurements high-temperature weldable strain

gages are free-filament wire strain gages pre-bonded

to shim stock using flame sprayed alumina. The gages

can be welded to the test structure using a capacitive

discharge spot welder (such as Micro-Measurements

Model 700), permitting easy installation in the field,

especially on large structures. High-temperature weldable

strain gages are excellent in applications where protection

against moisture is not required. The fatigue resistance

of this bonded wire strain gage makes it the best choice

for dynamic, impact or vibratory strain measurements

to 1800°F (980°C). Their use in measuring static strains

should be avoided.
High-temperature weldable strain gages are available

with grids of Nichrome V (N) or Pt8W (E) alloys. They

can be ordered with either of two types of preattached

high-temperature insulated cable.

GAGES WITH M-SERIES LEADWIRES

GAGES WITH F-SERIES LEADWIRES

Complete assembly consists of a free-filament gage

bonded to a shim with an integral high-temperature

cable with chromel/alumel wires. The mineral insulated,

two-conductor cable with an Inconel metal jacket is

rated to 1800°F (980°C) and offers excellent protection in

harsh environments. While the ends are sealed to avoid

moisture absorption during shipping or storage, care

should be taken when using M-Series cables to ensure

that the mineral insulation does not absorb moisture

during handling and application.

Complete assembly consists of a free-filament gage

bonded to a shim, a weldable transition terminal and

a high temperature cable with chromel/alumel wire.

A fiberglass-insulated braided, two-conductor cable

assembly is attached at the gage end through alumina

insulators strap-welded to the terminal shim, providing

a firm anchor for the cable at the gage end. The cable

conductors are threaded through lengthwise holes in the

alumina insulators and bonded to the insulators with high

strength ceramic cement to prevent wire movement at

the gage—cable weld junction. The fiberglass cable is

rated to 1200°F (650°C) and is used where fraying due

to vibration is not a concern. F-Series cables are more

flexible than M-Series cables.

FEATURES

• Measurement range to 2100°F (1150°C)
• Free-filament Kanthal alloy grids for bonding with

• Linear and Tee-rosette patterns

ZC-Series strain gages are etched Kanthal (Fe-Cr-Al

alloy) foil grids in free-filament form for high-temperature

applications. They are bonded with either ceramic

adhesives, or by the use of flame spray.
ZC-Series strain gages cannot be self-temperature

compensated, and a dummy compensating gage must

be used for minimizing of thermally induced apparent

strain (thermal output). Several patterns are available with

built-in compensating grids.

ZC-Series strain gages are supplied with a removable

high-temperature carrier for gage handling during

instal lation. All patterns have 1 in (25.4 mm) Nichrome

ribbon leads spot welded to the gage tabs for leadwire

attachment.

For use with compact specimens.

Shear Modulus Sensors are specifically designed to

accommodate the unique specimen geometries and

strain-field distributions encountered when testing

composite materials for shear properties. Two popular

specimens for in-plane shear modulus testing of

composites are the Iosipescu and compact designs.

The test section for both types is described as the

area between two opposing notches. The Iosipescu

specimen has a distance between the notch roots of

0.45 in (11.4 mm); for the compact design this distance

is 0.75 in (19 mm). Both of these specimens have an

inherently nonuniform shear-strain distribution in their test

zone. Determining shear modulus requires extracting an

average shear-strain value from this nonuniform strain

field. Since strain gages have the unique characteristic

of integrating the surface strain field under their grids,

average specimen strain is automatically obtained by

spanning the entire length of either specimen’s test

section.
Two 500 Ω ±0.4%, ±45° shear-gage configurations are

available for both the Iosipescu and compact specimen

designs. The planar configuration, with side-by-side

grids, is constructed with a standard N2 backing and

Option SP61 (soft, copper lead ribbons and polyimide film

encapsulation). The stacked configuration is produced

with a special backing, A2. This backing is similar to

N2 but is fully encapsulated with a polyimide film and

includes integral soft, copper lead ribbons (like those

provided by Option SP61). The stacked configuration is

offered to best simulate strain measurement at a point.

The stacked gages are supplied in a quarter-bridge

arrangement so that independent gage measurements

can be made if necessary. When connected in a half-

bridge circuit, the stacked construction inherently

provides temperature compensation and insensitivity to

normal strains. Due to the increased stiffness of a stacked

sensor, compared to one having only a single layer, an

evaluation of the test conditions and requirements should

be made to ensure that the gage will not compromise

accuracy by significantly reinforcing low-modulus and/or

thin specimens.

The EGP-Series Embedment Strain Gage is specially

designed for measuring mechanical strains inside

concrete structures. The sensing grid, constructed of a

nickel-chromium alloy (similar to Karma), has an active

gage length of 4 in (100 mm) for averaging strains in

aggregate materials. A rugged 5 in (130 mm) outer body

of proprietary polymer concrete resists mechanical

damage during pouring, minimizes reinforcement of

the structure, and provides protection from moisture

and corrosive attack. The grid, cast within the polymer

concrete to ensure maximum strain sensitivity, is self-

temperature-compensated to minimize thermal output

when installed in concrete structures. Each gage

incorporates a heavy-duty 10 ft (3 m) cable with 22-AWG

(0.643 mm dia.) leadwires; a three-wire construction to

the sensing grid helps minimize temperature effects in

the instrumentation leads. Special lengths of preattached

cable will be quoted upon request. Micro-Measurements

M-LINE accessory cable 322-DJV is available for adding

cable length in the field.
Rugged and reliable, EGP-Series Strain Gages are

available in both 120-ohm (EGP-5-120) and 350-ohm

(EGP-5-350) resistances.

Products with designations and options shown in bold are not RoHS compliant.

In addition to the standard line of temperature sensors described above, Micro-Measurements can furnish almost any

type of sensor pattern desired, in a wide range of resistances. Contact our Applications Engineering Department for

details.

Resistance thermometry is a widely employed method

of measuring temperature, and is based on using a

material whose resistivity changes as a function of

temperature. Resistance Temperature Detectors (RTD’s)

have fast response time, provide absolute temperature

measurement (since no reference junctions are involved),

and are very accurate. Their measurement circuits are

relatively simple, and the sensors, when properly installed,

are very stable over years of use.
Micro-Measurements resistance temperature sensors

are constructed much like wide-temperature-range

strain gages. The standard sensors utilize nickel or

nickel/manganin grids, although special-purpose gages

are also available in Balco

alloy or copper foil grids.

These temperature sensors are bonded to structures

using standard strain gage installation techniques,

and can measure surface temperatures from –452° to

approximately +500°F (–269° to +260°C). Because of their

extremely low thermal mass and the large bonded area,

the sensors follow temperature changes in the structural

mounting surface with negligible time lag.

Balco is a trademark of the W.B. Driver Company

TG TEMPERATURE SENSORS

TG Temperature Sensors are normally selected for

measurements from –320° to +500°F (–195° to +260°C).

The sensing grid utilizes a high purity nickel. Three basic

constructions are offered:
ETG Sensors have a polyimide carrier for flexibility. It is

available as an encapsulated gage with exposed solder

tabs (Option E), or with integral printed-circuit terminals

(Option W).
The WTG Sensor incorporates integral leadwires and a

high-temperature epoxy-phenolic matrix (reinforced with

glass fiber) which fully encapsulates the grid.
The WWT-TG Sensor is a slightly larger version of the

WTG, but preattached to a 0.005-in (0.13-mm) thick

stainless steel shim. This gage can be welded or bonded

to a structure.
The resistance at +75°F (+23.9°C) is 50Ω ±0.3% for the

ETG and WTG Sensors; and 50Ω ±0.4% for the WWT-TG

Sensors.
Maximum operating temperature for ETG Sensors with

Option E is +450°F (+230°C), and +350°F (+175°C) for

Option W. All other types are +500°F (+260°C).

Temperature Sensors and LST Networks

Special Use Sensors—Temperature

TG LST MATCHING NETWORKS

The temperature coefficient of resistance of nickel sensors

is very high but nonlinear as indicated in the graph.

The sensor resistance can be measured directly and

converted to temperature with the charts supplied in Tech

Note TN-506, but since TG Sensors are commonly used

along with strain gages, special matching networks have

been developed to use with strain gage instrumentation.
These LST Matching Networks are small passive

devices encapsulated in a molded epoxy case. They

are connected between TG Temperature Sensors and

the strain gage readout instrumentation to perform the

following three functions:

1. Linearize the gage resistance versus temperature.
2. Attenuate the resistance change slope to the equivalent

of 10 or 100 microstrain per degree F or C for a gage

factor setting of 2.000 on the strain indicator.

3. Present a balanced 350-ohm half-bridge circuit to the

strain indicator at the reference temperature of 0°F

(Fahrenheit networks) or 0°C (Celsius networks).

In order to optimize performance, separate network

designs are available for cryogenic and normal

temperature ranges. Environmental temperature range

of LST networks is –65° to +250°F (–55° to +125°C).

Standard strain gage instrumentation, such as the

Micro-Measurements Model P3, is ideal for use with

these sensors, eliminating the need to purchase separate

readout devices.

Temperature Sensors and LST Networks

Special Use Sensors—Temperature

CLTS-2B TEMPERATURE SENSORS

The Cryogenic Linear Temperature Sensor (CLTS) is

recommended for best accuracy over the temperature

range of –452° to +100°F (–269° to +40°C). The CLTS-2B

is a small surface thermometer gage consisting of two thin

foil sensing grids laminated into a glass-fiber-reinforced

epoxy-phenolic matrix, and electrically wired in series.

The two alloys are special grades of nickel and manganin

that are processed for equal and opposite nonlinearities

in resistance versus temperature characteristics. The

CLTS-2B is fabricated with integral printed-circuit

terminals to provide strong, convenient attachment points

for the leadwires. Gage construction is illustrated at right.
Because of its low thermal mass and thin construction,

the CLTS-2B responds quickly and accurately to

temperature changes in the surface to which it is bonded.

Special design features protect the sensor from damage

due to thermal shock, even during plunges from room

temperature directly into liquefied gases, including LHe at

–452°F (–269°C).

Avoid prolonged exposure of the CLTS-2B to temper-

atures above +150°F (+65°C) as this may adversely

affect characteristics of the manganin material. The

maximum recommended curing temperature of the

bonding adhesive is two hours at +200°F (+95°C).

CLTS-2B SENSITIVITY

The nominal resistance of the CLTS-2B is 290.0 ohms

±0.5% at +75°F (+23.9°C). The resistance decreases

linearly with temperature, reaching a nominal value of

220.0 ohms at –452°F (–269°C). This represents a change

of 70 ohms for 527°F, or a slope of 0.1328 ohms per

degree F; the corresponding slope on the Celsius scale is

0.2391 ohms per degree C. With proper instrumentation

a resolution of 0.01° can be easily achieved. Data readout

can be accomplished by directly monitoring resistance

change with an appropriate resistance measuring

instrument.

CLTS MATCHING NETWORKS

When used in conjunction with

bonded strain gages, it is often

most convenient to modify the

CLTS output with a simple, passive

resistance network that can be used

with strain gage instrumentation as

described with the TG Sensors. The

sensitivity can be adjusted to 10 microstrain per degree

C (CLTS-N-C); with a resolution of 0.1° when used with

most strain indicators. This type of network also provides

a high degree of leadwire compensation. Environmental

temperature limits for CLTS Networks are –65° to +250°F

(–55° to +125°C).

Manganin Patterns

Special Use Sensors—Manganin Pressure Sensor

Manganin is a copper-manganese-nickel alloy with a

low strain sensitivity, but a relatively high sensitivity to

hydrostatic pressure. Resistance change as a function

of applied pressure is linear to extremely high pressures.

This characteristic has been utilized in the construction

of high-range fluid pressure cells using manganin wire for

many years.
Manganin gages are used extensively in high-pressure

shock wave studies ranging from 1 to over 400 kilobars

(1 bar = 14.5 psi = 100 000 N/m

). In conventional

applications, the gage is bonded between two flat metallic

or polymer plates.
Micro-Measurements offers a large selection of gages for

shock wave studies, manufactured from specially treated

shunt stock manganin foil. The ultrathin construction

offers several advantages over the wire type, including:
• Improved repeatability from gage to gage, due to

precisely defined grids manufactured from the same lot

of foil.

• Faster response times (nanosecond rise times have

been recorded).

• Smaller, high resistance grids.
• Minimal distortion of the pressure wave when mounted

in high-modulus materials.

TECHNICAL INFORMATION

Nominal pressure sensitivity of Micro-Measurements

manganin foil gages is 0.27% per kilobar (0.0027

ohm/ohm/kb). Long signal transmission cables, low

signal levels, and high electrical noise complicate

the measurement. Most of these gages are designed

for impedance matching to 50-ohm coaxial cable.

The 210AW pattern illustrated has been used with

excitation currents exceeding 6 amperes for periods to

100 microseconds.
The 580SF pattern was designed specifically for

investigating the effects of sweeping explosive waves.

With the target intentionally tilted at a small angle to the

wave front, the pressure wave traverses the grid in the

direction toward the leads.
Micro-Measurements manufactures manganin foil gages

in several backing materials. The backing material is

normally selected to minimize the mechanical impedance

mismatch within the target.

L backing

is a glass-fiber-reinforced epoxy-phenolic

approx. 0.002 in (0.050 mm) thick. Although commonly

used in the 1- to 15-kilobar range, its usefulness is not

limited to this extent. The backing is ideal for use in

quartz-phenolic transducers since it does not present a

significant impedance discontinuity. L-backed gages may

be used in high-mechanical-impedance materials with the

understanding that rise-time limitations may exist due to

an impedance mismatch between the sensor and the test

material. An encapsulated version (Option SP60), with

only the tab ends exposed for soldering, is available.

N2 backing

is nominally 0.0008 in (0.020 mm) thick

polyimide film. This backing is rugged, highly flexible, and

easy to handle. It is suited to very-low-kilobar pressure

ranges.

J2 backing

is an encapsulated version of the N2, with the

ends of the tabs exposed.

Crack Detection Patterns

Special Use Sensors—Crack Detection Sensors

For repetitive use on identical structural shapes, special patterns may be designed to fit the expected crack

formation area. Contact our Applications Engineering Department for details.

CD-Series Crack Detection Gages are designed to

provide a convenient, economical method of indicating

the presence of a crack, or indicating when a crack has

progressed to a predetermined location on a test part

or structure. By employing several CD gages, it is also

possible to monitor the rate of crack growth; however,

Crack Propagation Gages would normally be selected for

that purpose.
In some applications, thin copper wires bonded to the

test structure are used to provide a low-cost method of

detecting crack initiation or propagation. Because of the

behavior of copper wire, however, this method suffers

from two limitations: (a) the crack tip may progress

considerably beyond the wire without breaking the strand,

and (b) in areas of high cyclic strains, the wire may fail in

fatigue without crack initiation in the specimen. CD-Series

Crack Detection Gages are designed to overcome both of

these limitations.
CD-Series gages consist of a single strand of high-

endurance alloy. A crack propagating beneath the gage

will induce local fracture of the sensing strand and open

the electrical circuit. When the CD gage is installed at

critical locations on a test part or structure and used as a

sensing element in a control system, the signal can serve

to alter a test sequence or to alert an operator to incipient

component failure.

CONSTRUCTION

Two gage constructions are currently available:
The CD-02 is made of beryllium copper alloy laminated to

polyimide, and offers a low-resistance sensing element.

Select the CD-02 type for maximum conformability to

irregular surfaces and ease of soldering, when greatest

fatigue life is not required.
The CD-23 type is constructed of isoelastic alloy

laminated to a glass-fiber-reinforced backing for

applications where the highest endurance is required.

The superior fatigue life of the isoelastic alloy allows

the CD-23 to be used in high cyclic strain fields without

premature failure, while maintaining high sensitivity

to crack formation under the gage. This gage is less

conformable than the CD-02 and requires use of SS-Flux

for tinning of solder tabs for leadwire attachment.
Crack Detection Gages are available with various strand

lengths; from 0.4 in (10 mm) for applications where space

is limited, to 2.0 in (50 mm) for use where the direction

of crack propagation, or the point of crack initiation, is

uncertain.
Resistance of the CD Series is nominally 0.05Ω/mm of

active strand length for beryllium copper and 1Ω/mm for

isoelastic gages.
The normal operating temperature range is –320° to

+250°F (–195° to +120°C).

ADHESIVES

Conventional strain gage adhesives are suitable for

bonding CD-Series gages. M-Bond 600, 610, or 43-B

are preferred for excellent performance over the widest

operating temperature range. However, M-Bond

AE-10 and AE-15 are also suitable where in-service

temperatures will not exceed +200°F (+95°C). M-Bond

200 is satisfactory for fast installation, but should not be

used for long-term testing.

PROTECTIVE COATINGS

Corrosion, which can cause premature filament failure, is

greatly accelerated in the presence of high cyclic strain

fields. For long-term use, it is essential to protect the

crack detection gage from atmospheric corrosion and

other contamination.
M-Bond 43-B is an excellent protective coating when

the bonding adhesive, leadwire insulation and solder can

tolerate the cure temperature. If lower cure temperatures

are necessary, M-Bond AE-10 and AE-15 are

recommended. When in-service environmental conditions

are not extreme, a softer coating may prove perfectly

adequate. Either 3140 RTV or M-Coat D would be a good

choice in these instances.

Crack Propagation Patterns

Special Use Sensors—Crack Propagation Sensors

Crack Propagation Gages provide a convenient method

for indicating rate of crack propagation in a test part or

structure. The CPA, CPB, and CPC patterns consist of a

number of resistor strands connected in parallel. When

bonded to a structure, progression of a surface crack

through the gage pattern causes successive open-

circuiting of the strands, resulting in an increase in total

resistance. The CPA pattern incorporates 20 resistor

strands; the CPB, with the same basic configuration,

incorporates ten. Both series produce stepped increases

in resistance with successive open-circuiting as indicated

in the charts below. In applications where space permits,

the CPC pattern may be preferred because of greater

uniformity of increases in total resistance with successive

strand fractures.
The resistor strands of the CPD pattern operate

independently, each producing an open circuit when

fractured. This type of gage allows the user to electrically

predetermine a specific point in the fracturing process

at which the instrumentation will perform some type of

altering function.

GAGE CHARACTERISTICS

Crack Propagation Gages have a nominal gage thickness

of only 0.0017 in (0.043 mm). The high-endurance

K-alloy foil grid has a single cycle strain range of up to

±1.5% with a fatigue life of greater than 10

cycles at

±2000 microstrain. The standard backing is a glass-fiber-

reinforced epoxy matrix. These gages are useful through

the temperature range of –452°F (–269°C) to over +450°F

(+230°C).
Since exact self-temperature compensation is

unnecessary in crack propagation studies, all of these

gages are supplied in 09 S-T-C.
Crack Propagation Gages feature small copper pads on

the tabs for ease of soldering.

ADHESIVES AND PROTECTIVE COATINGS

Crack Propagation Gages should be installed with

a solvent-thinned adhesive incorporating a cure

temperature of at least +300°F (+150°C). M-Bond 600 or

610 adhesives are recommended for use over the widest

temperature range. Handling tape should not be applied

over the grid or soldering tabs during installation. Room-

temperature-curing adhesives are not recommended for

use with Crack Propagation Gages.
Protective coating selection considerations are similar

to those for CD-Series Crack Detection Gages.

Refer to appropriate datasheet for protective coating

recommendations.

Linear Displacement Sensors

Special Use Sensors—Linear Displacement Sensors

FEATURES

• Infinite resolution
• True output linearity over the entire measurement range
• Low operating forces
• Excellent stability and temperature compensation

DESCRIPTION

Micro-Measurements Linear Displacement Sensors use a

fully active 350-ohm strain-gage bridge to sense spindle

displacement, giving infinite resolution and excellent

linearity. They are compatible with all standard strain-gage

instrumentation with bridge excitation from 2 to 10 volts.

With a selection of models having full-scale ranges from

1/4 in (5 mm) to 4 in (100 mm), Linear Displacement

Sensors feature a unique design that produces maximum

operating forces of less than 1 lb (4.4 N). Available

with specially designed mounting fixtures, these

versatile sensors are ideally suited for use in research,

manufacturing and process control applications.

ACCURACY

Micro-Measurements Linear Displacement Sensors

produce an output voltage proportional to a captive,

guided spindle displacement by means of a 350-ohm

strain gage bridge with four active arms. This arrangement

provides excellent temperature compensation and

linearity.

COMPATIBILITY

Micro-Measurements Linear Displacement Sensors

exhibit the same inherent advantages for linearity,

versatility and precision as many other strain-gage-based

sensors. As such, they are systems-compatible with a

wide range of commonly used sensors for pressure, load,

acceleration, vibration, etc. and normally utilize the same

instrumentation.

Strain Gage Installation

Micro-Measurements Strain Gage Accessories

Micro-Measurements strain gages are produced under

rigidly controlled manufacturing conditions, with the

utmost care and attention given to ensuring the high level

of quality for which these gages have gained world-

wide recognition. However, the gages’ full potential

for accurate strain measurement can be realized only

when they are properly installed. There are, in fact, three

principal components in every strain gage installation:

(1) The strain gage itself, (2) the tools, materials, and

supplies (accessories) needed to install the gage,

and (3) the techniques employed in performing the

installation. Professional stress analysts have learned

from experience that compromising any of these may lead

to compromising the quality of the installation and the

accuracy of the strain data.
The well-established formula for making consistently

successful strain gage installations is quite simple:
• Select high-quality precision strain gages.
• Select professional-caliber accessories which

have been laboratory-tested and field-proven for

effectiveness and compatibility with the strain gages.

• Follow the installation procedures recommended by the

manufacturer of the gages and accessories.

A small sample of the Micro-Measurements strain gage

installation accessories is featured on the following two

pages. As indicated, the appropriate materials, supplies,

and tools are available for each important step in the

gage installation process—from preparing the surface of

the test piece to applying a protective coating over the

bonded and wired gage. All accessory items, whether

manufactured directly by Micro-Measurements or

specified for purchase from an outside supplier, are of

the highest quality, and have been designed or selected

specifically to help ensure successful installation of Micro-

Measurements strain gages.
Regular users of strain gages will want to request a

copy of Micro-Measurements Strain Gage Accessories

databook. This fully illustrated catalog describes the

complete line of gage installation accessories and related

equipment. In addition to detailed product descriptions

and specifications, it includes, where applicable,

extensive recommendations for the appropriate selection

and application of the accessories. Micro-Measurements

Strain Gage Accessories databook is available on

request from our Applications Engineering Department. A

complete listing is available on our website.

Considerations for Instrument Selection

outputs suitable for multiple channel, simultaneous,

dynamic recording. All of these systems can be used in

conjunction with a variety of recording devices.

DIGITAL DATA SYSTEMS

Depending on their design, digital data systems can be

used for measurement of static, dynamic, or both kinds

of signals. Micro-Measurements offers three digital data

systems, each controlled with StrainSmart

software and

other third-party software.
System 7000 is a high performance dynamic data

acquisition instrument with measurement accuracy of

±0.05% of full scale. Each sensor card employs a 24-bit

analog to digital converter enabling 0.5 microstrain

resolution. Scan rates up to 2048 samples per second are

available for simultaneous reading of all sensor inputs.

A combination of analog and flexible Finite Impulse

Response (FIR) filters are available to provide adequate

anti-alias filtering at all scanning rates. Electronically

selectable bridge completion resistors allow the user to

choose between 120-, 350-, and 1000-ohm strain gages

through software selection. System 7000 is capable of

self-calibration with a removable calibration reference.
System 8000 is a versatile, precision data acquisition

instrument system intended for static and dynamic test

and measurement applications. The system includes a

scanner with 8 channels of data acquisition. A 10-foot

crossover Ethernet cable is also included. The scanners

may be used separately or up to 16 scanners can be

used concurrently for a maximum of 128 channels. Each

channel can be configured, via software, to accept signals

from strain gages or strain-gage-based transducers,

thermocouples, or high level voltage sensors. Strain

gage channels accept full-, half-, or quarter-bridge

configurations and have the required bridge completion

components for 120-, 350-, and 1000- ohm bridges.

Each scanner operates independently; multiple scanners

are not synchronized. The data is processed in a modern

24-bit digital signal processor and filtering is performed

using Finite Impulse Response (FIR), multi-stage filters.

This provides excellent noise rejection and stability and

unsurpassed measurement accuracy.
System 9000 from Micro-Measurements is a versatile,

precision data acquisition instrument system intended for

dynamic test and measurement applications. The system

includes a scanner with 12 channels of strain gage (strain

gauge) data acquisition and 4 configurable slots for high

level voltage sensors, thermocouples, and piezoelectric

transducers (charge mode and voltage mode). Strain

gage (strain gauge) channels accept full-, half-, or

STRAIN INDICATORS AND CALIBRATORS

Basic instrumentation requirements call for stability,

accuracy and high resolution when making measurements

under static loading conditions, and particularly where

measurements are to be taken over long periods of time.

Micro-Measurements offers our Model P3 Strain Indicator

and D4 Data Acquisition Conditioner to meet these

demanding criteria.
The Model P3 Strain Indicator and Recorder is a

portable, battery-operated instrument while our D4 is a

USB-powered instrument that connects to a personal

computer. Both are capable of simultaneously accepting

four inputs from quarter-, half-, and full-bridge strain-gage

circuits, including strain-gage-based transducers. A highly

stable measurement circuit, regulated bridge excitation

supply, and precisely settable gage factor enable

measurements of ±0.1% accuracy and 1 microstrain

resolution. The P3 can also be configured and operated

directly from your PC with a separate software application

included with each instrument. The D4 also has a

separate software application and is programmable for

custom applications.

SIGNAL CONDITIONING AMPLIFIERS

When signals are produced by dynamically applied

loads at frequencies above 0.1 Hz, or are transients,

measuring instrumentation requires adequate frequency

response, and a wide amplifier gain range for output

to the appropriate recording or display device. Such

an instrument consists of an amplifier and signal

conditioner with a built-in or shared power supply.

Individual units are normally required for each channel

when simultaneous recording or multiple channels are

needed. With the output sent to a suitable display device,

signal conditioning amplifiers can be used for making

long-term measurements under static loading conditions,

when maximum stability and accuracy are not primary

considerations.
The 2100, 2200, and 2300 Systems accept low-level

signals, and condition and amplify them into high-level

Gage Series—Stress Analysis Gages

Technical Data

GAGE SERIES

All Micro-Measurements strain gages incorporate

precision foil grids mounted on organic backing materials.

The strain-sensing alloys and backing materials cannot

be arbitrarily combined in specifying a gage type. Instead,

a selection must be made from among the available

gage systems, or series, where each series generally

incorporates special design or construction features,

as well as a specific combination of alloy and backing

material.
Descriptions of all standard gage series are given on the

following pages, along with performance specifications

and application notes. The information includes, in each

case, the alloy and backing combination employed, as

well as the principal construction features common to

the series. The allowable strain range is specified, and

operating temperature ranges are recommended for

different types of applications.
The plots of cyclic strain level versus number of cycles

shown for each series represent general guidelines

for the nominal fatigue characteristics. This data is a

function of gage size with the upper curve indicative of

larger gage patterns, and the lower curve of smaller gage

patterns. Since the fatigue life of a strain gage is subject

to special interpretation, reference should be made

to Micro- Measurements Tech Note TN-508, “Fatigue

Characteristics of Micro-Measurements Strain Gages”, for

a full understanding of the plotted data.
The fatigue curves on the following pages correspond

to fully reversed strain levels. They can also be

applied, approximately, to unidirectional strains and to

combinations of mean and variable strains by derating

the peak-to-peak amplitude by 10%. As an example, a

fully reversed strain range of ±1500μ

is approximately

equivalent in gage fatigue damage to strain levels of:

0 to +2700μ

0 to –2700μ

–200 to +2500μ

However, a mean strain which increases in the tensile

direction during cycling will lead to much earlier failure.
It must be noted that all performance specifications

for strain gages are nominal, since the behavior of

a particular gage may be modified by installation or

application circumstances. Moreover, the specifications

apply primarily to gages of 0.125 in (3 mm) gage length

and larger, and without optional features, unless otherwise

indicated.

EA SERIES

EA-Series constantan gages are widely used in general-purpose experimental stress

analysis applications. The basic gage is of open-faced construction on a 0.001 in

(0.025 mm) tough, flexible cast polyimide backing. The strength and heat resistance

of this backing provide excellent handling and performance qualities. This series is

available in the widest range of patterns and will usually be the lowest in cost for a

particular pattern design. A large number of options may be obtained for EA-Series

gages, covering various forms of lead attachment and protective encapsulation. The

backing is treated for strong bond formation with all standard strain gage adhesives.

Strain limits are approximately ±5% for gages of 1/8 in (3 mm) or greater gage length

and ±3% for smaller sizes.

Gage Series—Stress Analysis Gages

Technical Data

CEA SERIES

CEA-Series gages are the most widely accepted for use in general-purpose experimental

stress analysis applications in the world today. These polyimide encapsulated

constantan gages feature large, rugged, copper-coated tabs. This construction provides

optimum capability for attaching leadwires directly to the tabs, eliminating the need

for separate terminals. In most applications, the CEA Series is preferred over the EA

Series with options such as E, L, LE and W. Nominal single-plane gage thickness is

0.0027 in (0.069 mm); stacked rosettes, 0.0039 in (0.099 mm). The extremely tough but

flexible cast polyimide carrier can be contoured to almost any radius. Strain limits are
approximately ±5% (50 000 μ

) for gage lengths 1/8 in (3 mm) or greater, and ±3% for

smaller sizes.

formation. The N2A Series has an elongation capability of approximately ±3%. These

gages are intended for use in elastic strain fields. This series is primarily available for

Gage Series—Stress Analysis Gages

Technical Data

WA SERIES

WA-Series gages are fully encapsulated constantan, equipped with integral, high-

endurance beryllium copper leadwires. The backing and encapsulation matrix consists

of a high-temperature epoxy-phenolic resin system reinforced with glass fibers. Overall

gage thickness is approximately 0.0028 in (0.071 mm). The WA construction provides

a gage that is strong and easy to handle, though not as flexible as the EA type. The

backing is treated for strong bond formation with all standard strain gage adhesives. The

strain range is limited to approximately ±1 to 2% by the hard, creep-resistant matrix.

WA-Series gages are primarily intended for high accuracy measurements over wider

temperature ranges and in more difficult environments than other forms of constantan

gages. Option W is available on some WA-Series gages, but will restrict the fatigue life

to some extent. Heat-curing adhesives such as M-Bond 600 or 610 are recommended

when full-temperature-range capabilities are required.

SA SERIES

SA-Series gages are fully encapsulated constantan similar to WA-Series gages, but with

solder dots instead of leadwires. The matrix is somewhat thinner than the WA type, with

an overall gage thickness of approximately 0.002 in (0.05 mm). The solder is a lead-tin-

silver alloy which melts at approximately +570°F (+300°C). These gages are typically

used in stress analysis applications when mounting space is restricted. The solder dot

connections permit small jumper wires to be attached from any direction, and the matrix

can be field-trimmed very close to the pattern since no integral leadwires are involved.

Because of the exposed solder dots, SA-Series gages are not as well protected

in extreme environments as the WA type. The WA Series is superior in maximum

temperature capability and fatigue life. No leadwire options are available in this series.

Strain limits are approximately ±1 to 2%. Heat-curing adhesives such as M-Bond 600 or

610 are recommended for full-range performance.

EP SERIES

EP-Series gages are specifically designed for use in the measurement of large strains,

>3–5%. The basic gage is of open-faced construction on a 0.001 in (0.025 mm) tough,

flexible, high-elongation cast polyimide backing. The sensing grid is a special grade

of fully annealed constantan foil for maximum ductility. This gage series is available in

08 and 40 compensations, for use on metals and plastic, respectively. Exact values of

self-temperature compensation are usually not important in post-yield work because

the thermal output error is very small compared to the large strain levels being

measured. Strain limits for EP-Series gages are approximately ±20% for gages of 1/8 in

(3 mm) or greater gage length, and ±10% for smaller sizes. Optional features generally

degrade elongation capabilities. EP-Series gages can be obtained on special order

with all options offered on the equivalent EA-Series pattern. M-Bond A-12 adhesive is

recommended for full elongation capability.

ED SERIES

ED-Series gages are used in general-purpose dynamic-only strain measurement.

They are openfaced construction on a thin, 0.001 in (0.025 mm), tough, flexible cast

polyimide backing. The isoelastic grid alloy has a high strain sensitivity, and gage

factor is approximately 3.2. The extremely high temperature coefficient of resistance
(thermal output of approximately 80μ

/°F (145μ

/°C)) does not normally permit static

measurements to be made with isoelastic gages. The outstanding features of the ED

Series are excellent handling properties, high flexibility, good fatigue life, and relatively

low cost. A wide range of options is available, covering various forms of lead attachment

and protective encapsulation. Leadwires must be handled and installed with care to

avoid reduction in fatigue life. All isoelastic gages tend to generate error signals in

magnetic fields, since the alloy is both magnetic and magnetostrictive. Strain limits for
ED gages are approximately ±1%, but increasing nonlinearity above ±5000μ

normally

restricts this type of gage to measurement of dynamic, elastic strain levels.

WD-Series gages are fully encapsulated isoelastic alloy with integral, high-endurance

beryllium copper leadwires. The matrix is a high-temperature epoxy-phenolic resin

system reinforced with glass fibers. Overall gage thickness is approximately 0.0028

in (0.071 mm). These gages are excellent in dynamic strain measurement over wide

temperature ranges. The WD Series is considerably less flexible than the ED type,

but is useful over a wider temperature range and in more severe environments. The

encapsulation matrix and integral high-endurance leadwires provide higher fatigue life

than ED-Series gages. No standard options are available. Strain limits for WD-Series
gages are approximately ±5000μ

. Heat-curing adhesives such as M-Bond 600 or 610

SD-Series gages are fully encapsulated isoelastic alloy similar to WD-Series gages, but

with an overall thickness of approximately 0.002 in (0.05 mm). The solder is a lead-tin-

silver alloy which melts at +570°F (+300°C). The SD Series is primarily used over the

WD type when the matrix must be trimmed very close to the gage pattern because of

restricted mounting space. There are no integral leadwires to restrict trimming of the

lower edge of the matrix, and attachment wires can be routed to the solder dot tabs

from any direction. Both maximum operating temperature and fatigue life are somewhat

lower than in the WD Series because of the exposed solder dots. Strain limits are
approximately ±1%, but nonlinearity becomes increasingly severe above ±5000μ

Gage Series—Stress Analysis Gages

Technical Data

EK SERIES

EK-Series gages are K alloy, often employed in general-purpose testing where higher

resistances and grid stability are required, particularly at elevated temperatures. They

are normally selected for applications where reinforced laminate-backed gages lack

sufficient flexibility. EK gages are of openfaced construction on a 0.001 in (0.025 mm)

tough, flexible cast polyimide backing. The strong, heat-resistant backing provides

excellent handling and performance qualities, and is treated for good bond formation

with all standard strain gage adhesives. Heat-curing adhesives such as M-Bond 610

are recommended for full-temperature-range capabilities. Strain limits for this series are

approximately ±1.5%. EK gages are often selected instead of EA gages for improved

fatigue life. However, when maximum fatigue life is required, reinforced laminate-backed

K-alloy gages are recommended. Soldering to K-alloy is difficult, and duplex copper

pads or dots are included as a standard feature. Most options available on EA-Series

gages are offered with EK gages, but performance may be degraded.

WK SERIES

WK-Series gages are fully encapsulated K alloy, equipped with integral, high-endurance

beryllium copper leadwires. The matrix is a high-temperature epoxy-phenolic resin

system reinforced with glass fibers. Overall gage thickness is approximately 0.0028 in

(0.071 mm). WK-Series gages have the widest temperature range and most extensive

environmental capability of any general purpose strain gage of the self-temperature-

compensated type. Option W is available on many pattern designs, but will lower the

excellent cyclic endurance and maximum operating temperature of the basic WK gage.

Elevated temperature drift of these gages is very low to +600°F (+315°C), and the main

restriction at high temperatures is the limited life of the backing and adhesive due to

oxidation and sublimation. Strain limits for WK gages are approximately ±1.5%. High

temperature adhesives such as M-Bond 610 are required for full-range performance.

Gage Series—Stress Analysis Gages

Technical Data

SK SERIES

SK-Series gages are fully encapsulated similar to the WK-Series gages, but with solder

dots instead of leadwires. The matrix is somewhat thinner than the WK type, with an

overall thickness of approximately 0.002 in (0.05 mm). The solder is a lead-tin-silver

alloy which melts at approximately +570°F (+300°C). SK gages are primarily used when

mounting space is restricted. Performance is equivalent to the WK type, but over a lower

temperature range. Fatigue life of the SK Series is equivalent to the WK type, but more

care is required during leadwire attachment to avoid gage damage. The absence of

integral leadwires allows SK gages to be field-trimmed very close to the pattern size. No

leadwire options are available. Strain limits are approximately ±1.5%. Heat-curing

adhesives such as M-Bond 610 will provide best overall performance.

S2K SERIES

S2K-Series gages are fully encapsulated K alloy, equipped with large integral solder

dots. The backing and encapsulation are 0.001 in (0.025 mm) thick laminated high-

performance polyimide. The overlay fully encapsulates the grid and solder tabs. Large

[0.030 in (0.75 mm)] diameter solder pads are provided for ease of leadwire attachment.

Overall gage thickness is approximately 0.0025 in (0.065 mm) and the backing has

been specially treated for optimum bond formation. M-Bond 43-B is recommended for

S2K-Series gages if a cure temperature of +350°F (+175°C) is possible. Alternatively,

M-Bond AE-10/15, M-Bond 200, or M-Bond 600/610 may be used. The S2K Series has

an elongation capability exceeding ±1.5%. Designed primarily for use on composites,

these gages are normally produced in larger patterns and higher resistances.

Optional Features—Stress Analysis Gages

Technical Data

STANDARD OPTIONS

OPTION W

SERIES AVAILABILITY: EA, EP, WA, ED, WD, EK, WK

General Description:

This option provides encapsulation, and thin, printed circuit terminals at the tab end of the

gage. Beryllium copper jumpers connect the terminals to the gage tabs. The terminals are 0.0014 in (0.036 mm)
thick copper on polyimide backing nominally 0.0015 in (0.038 mm) thick. Option W gages are rugged and well
protected, and permit the direct attachment of larger leadwires than would be possible with open-faced gages.
This option is primarily used on EA-Series gages for general-purpose applications.

Solder:

+430°F (+220°C)

tin-silver alloy solder joints on E-backed gages, +570°F (+300°C) lead-tin-silver alloy solder joints on W-backed
gages.

Temperature Limit:

+350°F (+175°C) for E-backed gages, +450°F (+230°C) for W-backed gages.

Grid

Protection:

Entire grid and part of terminals are encapsulated with polyimide.

Fatigue Life:

Some loss in fatigue

life unless strain levels at the terminal location are below ±1000μ

Size:

Option W extends from the soldering tab

end of the gages and thereby increases gage size. With some patterns, width is slightly greater.

Strain Range:

With some gage series, notably E-backed gages, strain range will be reduced. This effect is greatest with EP
gages, and Option W should be avoided with them if possible.

Flexibility:

Option W adds encapsulation, making

gages slightly thicker and stiffer. Conformance to curved surfaces will be somewhat reduced. In the terminal
area itself, stiffness is markedly increased.

Resistance Tolerance:

On E-backed gages, resistance tolerance is

normally doubled.

OPTION E

SERIES AVAILABILITY: EA, ED, EK, EP

General Description:

Option E consists of a protective encapsulation of polyimide film approximately 0.001 in

(0.025 mm) thick. This provides ruggedness and excellent grid protection, with little sacrifice in flexibility.
Soldering is greatly simplified since the solder is prevented from tinning any more of the gage tab than is
deliberately exposed for lead attachment. Option E protects the grid from fingerprints and other contaminating
agents during installation and, therefore, contributes significantly to long-term gage stability. Heavier leads may
be attached directly to the gage tabs for simple static load tests. Supplementary protective coatings should still
be applied after lead attachment in most cases.

Temperature Limit:

No degradation.

Grid Protection:

Entire grid

and part of tabs are encapsulated.

Fatigue Life:

When gages are properly wired with small jumpers, maximum

endurance is easily obtained.

Size:

Gage size is not affected.

Strain Range:

Strain range of gages will be

reduced because the additional reinforcement of the polyimide encapsulation can cause bond failure before the
gage reaches its full strain capability.

Flexibility:

Option E gages are almost as conformable on curved surfaces

as open-faced gages, since no internal leads or solder are present at the time of installation.

Resistance

Tolerance:

Resistance tolerance is normally doubled when Option E is selected.

OPTION SE

SERIES AVAILABILITY: EA, ED, EK, EP

General Description:

Option SE is the combination of solder dots on the gage tabs with a 0.001 in (0.025 mm)

polyimide encapsulation layer that covers the entire gage. The encapsulation is removed over the solder dots
providing access for lead attachment. These gages are very flexible, and well protected from handling damage
during installation. Option SE is primarily intended for small gages that must be installed in restricted areas,
since leadwires can be routed to the exposed solder dots from any direction. The option does not increase
overall gage dimensions, so the matrix may be field-trimmed very close to the actual pattern size. Option SE
is sometimes useful on miniature transducers of medium- or low-accuracy class, or in stress analysis work on
miniature parts.

Solder:

+570°F (+300°C) lead-tin-silver alloy. To prevent loss of long-term stability, gages with

Option SE must be soldered with noncorrosive (rosin) flux, and all flux residue should be carefully removed with

M-LINE

Rosin Solvent after wiring. Protective coatings should then be used.

Temperature Limit:

No degradation.

Grid Protection:

Entire gage is encapsulated.

Fatigue Life:

When gages are properly wired with small jumpers,

maximum endurance is easily obtained.

Size:

Gage size is not affected.

Strain Range:

Strain range of gages will

be reduced because the additional reinforcement of the polyimide encapsulation can cause bond failure before
the gage reaches its full strain capability.

Flexibility:

Option SE gages are almost as conformable on curved

surfaces as open-faced gages.

Resistance Tolerance:

Resistance tolerance is normally doubled when Option

SE is selected.

Revision: 15-Nov-2015

Optional Features—Stress Analysis Gages

Technical Data

OPTION L

SERIES AVAILABILITY: EA, ED, EK, EP

General Description:

Option L is the addition of soft copper lead ribbons to open-faced polyimide-backed

gages. The use of this type of ribbon results in a thinner and more conformable gage than would be the case
with round wires of equivalent cross section. At the same time, the ribbon is so designed that it forms almost as
readily in any desired direction.

Leads:

Nominal ribbon size for most gages is 0.012 wide x 0.004 in thick (0.30

x 0.10 mm). Leads are approximately 0.8 in (20 mm) long.

Solder:

+430°F (+220°C) tin-silver alloy.

Temperature

Limit:

+400°F (+200°C).

Fatigue Life:

Fatigue life will normally be degraded by Option L. This occurs primarily

because the copper ribbon has limited cyclic endurance. When it is possible to carefully dress the leads so
that they are not bonded in a high strain field, the performance limitation will not apply. Option L is not often
recommended for very high endurance gages such as the ED Series.

Size:

Matrix size is unchanged.

Strain

Range:

Strain range will usually be reduced by the addition of Option L.

Flexibility:

Gages with Option L are not

as conformable as standard gages.

Resistance Tolerance:

Not affected.

OPTION LE

SERIES AVAILABILITY: EA, ED, EK, EP

General Description:

This option provides the same conformable soft copper lead ribbons as used in Option

L, but with the addition of a 0.001 in (0.025 mm) thick encapsulation layer of polyimide film. The encapsulation
layer provides excellent protection for the gage during handling and installation. It also contributes greatly to
environmental protection, though supplementary coatings are still recommended for field use. Gages with Option
LE will normally show better long-term stability than open-faced gages which are “waterproofed” only after
installation. A good part of the reason for this is that the encapsulation layer prevents contamination of the grid
surface from fingerprints or other agents during handling and installation. The presence of such contaminants
will cause some loss in gage stability, even though the gage is subsequently coated with protective compounds.

Leads:

Nominal ribbon size for most gages is 0.012 wide x 0.004 in thick (0.30 x 0.10 mm) copper ribbons. Leads

are approximately 0.8 in (20 mm) long.

Solder:

+430°F (+220°C) tin-silver alloy.

Temperature Limit:

+400°F

(+200°C).

Grid Protection:

Entire gage is encapsulated. A short extension of the backing is left uncovered at

the leadwire end to prevent contact between the leadwires and the specimen surface.

Fatigue Life:

Fatigue

life will normally be degraded by Option LE. This occurs primarily because the copper ribbon has limited cyclic
endurance. Option LE is not often recommended for very high endurance gages such as the ED Series.

Size:

Matrix size is unchanged.

Strain Range:

Strain range will usually be reduced by the addition of Option LE.

Flexibility:

Gages with Option LE are not as conformable as standard gages.

Resistance Tolerance:

Resistance

tolerance is normally doubled by the addition of Option LE.

LEADWIRE ORIENTATION FOR OPTIONS L AND LE

These illustrations show the standard orientation of leadwires relative to the gage pattern geometry for Options L and LE. The
general rule is that the leads are parallel to the longest dimension of the pattern. The illustrations also apply to leadwire orientation
for WA-, WK- and WD-Series gages, when the pattern shown is available in one of these series.

Optional Features—Stress Analysis Gages

Technical Data

OPTION P

SERIES AVAILABILITY: EA, N2A

General Description:

Option P is the addition of preattached leadwire cables to many patterns of EA Series

strain gages. Encapsulation seals small “jumper” leadwires at gage end, and cable insulation protects solder
joints at cable end. Option P virtually eliminates need for soldering during gage installation.

Leads:

A pair of 1

in (25 mm)

M-LINE

134-AWP (solid copper, polyurethane enamel) single conductor “jumper” leadwires.

Cable:

10 ft (3.1 m) of color-coded, flat, three-conductor 26-gauge (0.404 mm dia.), stranded, tinned copper with vinyl
insulation (similar to M-LINE 326-DFV). Solder: +430°F (+220°C) tin-silver alloy solder joints, “jumper” to gage.
Cable conductors and “jumpers” joined with +361°F solder beneath cable insulation. Exposed leadwires on
unattached end of cable are pretinned for ease of hookup.

Temperature Limit:

–60° to +180°F (–50° to +80°C);

limited by vinyl insulation on cable.

Grid Encapsulation:

Entire grid and tabs are encapsulated.

Fatigue Life:

Fatigue life will normally be degraded by Option P, primarily because the copper “jumper” wires have limited
cyclic endurance.

Pattern Availability:

Most EA-Series single-grid patterns that are 0.062 in (1.5 mm) or

greater gage length, with parallel solder tabs on one end of the grid, and suitable for encapsulation. (Consult
our Applications Engineering Department for availability of Option P on other gage series/patterns, and for
nonstandard cable lengths.)

Size:

Matrix size is unchanged.

Strain Range:

Strain range will usually be reduced

by the addition of Option P.

Flexibility:

E-backed gages with Option P are not as conformable as standard

gages.

Resistance Considerations:

Each conductor of the cable has a nominal resistance of 0.04 ohm/ft (0.13

ohm/m). Gage resistance is measured at gage tabs.

Gage Factor:

Gage factor is determined for gages without

preattached cable.

Resistance Tolerance:

Resistance tolerance is normally ±0.5% for single-element gages,

and ±0.6% for multiple-grid gages.

OPTION P2

SERIES AVAILABILITY: CEA

General Description:

Option P2 is the addition of preattached leadwire cables to CEA-Series strain gages.

Option P2 virtually eliminates need for soldering during gage installation.

Cable:

10 ft (3.1 m) of color-coded, flat,

three-conductor 30-gauge (0.255 mm), stranded, tinned copper with vinyl insulation (similar to

M-LINE

330-DFV).

Solder: +361°F (+180°C) tin-lead alloy solder joints. Exposed leadwires on unattached end of cable are pretinned
for ease of hookup.

Temperature Limit:

–60° to +180°F (–50° to +80°C); limited by vinyl insulation on cable.

Grid

Encapsulation:

Entire grid is encapsulated. (Solder tabs are not encapsulated.)

Fatigue Life:

Fatigue life will

normally be unchanged by Option P2.

Pattern Availability:

Most CEA-Series single- and multiple-grid patterns.

Size:

Matrix size is unchanged.

Strain Range:

Standard for CEA-Series gages.

Flexibility:

No appreciable

increase in stiffness.

Resistance Considerations:

Each conductor of the cable has a nominal resistance of 0.1

ohm/ft (0.35 ohm/m). Gage resistance is measured at gage tabs.

Gage Factor:

Gage factor is determined for

gages without preattached cable.

Resistance Tolerance:

Not affected.

OPTION S

SERIES AVAILABILITY: EA, ED, EP

Precisely formed hemispherical solder dots are installed in the center of each solder tab. This feature facilitates soldering by
providing a pretinned area for lead attachment. A film of adhesive or appropriate protective coating is normally applied over the
gage before soldering, and this prevents the solder from spreading on the tab when leads are reinstalled. After the top coating
has been cured, the solder dot is easily exposed for soldering by scraping with a scalpel or by simply post-tinning. Solder used
for the dots is +570°F (+300°C) lead-tin-silver alloy. Dot diameter varies somewhat with tab size but is usually about 0.02 in (0.5
mm). Temperature limit for this feature is +500°F (+260°C). Because the solder dots result in much greater soldering uniformity, the
variable fatigue life factor, which results from excessive solder on the gage tabs, is eliminated. Solder dots are small and interfere
very little with flexibility and conformability of strain gages.

OPTION W3

SERIES AVAILABILITY: EA, EP, WA, ED, EK, WK

This feature is identical to Standard Catalog Option W, except that the printed circuit wiring terminals have three solder pads, two
of which are electrically common. These terminals facilitate the connection of three-conductor cable for single active gage circuits
using the three-wire lead system. Many of the gage patterns which are marked as available with Option W in the General-Purpose
Strain Gage Listings are available with three-pad terminals.

Optional Features—Stress Analysis Gages

Technical Data

OPTION R

SERIES AVAILABILITY: ALL

The resistance of each gage is separately measured with an accurate digital ohmmeter and the exact value is recorded on
the transparent folder that contains the gage. Resistance is given to the nearest 0.01 ohm, and the overall absolute accuracy
is ±0.05% or better for gages of 60-ohm or greater resistance; thus allowing the user to select gages very closely matched in
resistance from the total group of gages purchased. The necessary order quantity can be estimated for any matching requirements
by assuming an even distribution of resistance values through the tolerance band, which is unchanged. Note: This feature is less
effective for open-faced gages without leadwires or solder dots because of the uncertainty in leadwire position on the tabs with
user-installed leadwires.

SPECIAL OPTIONS

OPTIONS SP11, 12, 13, 14

SERIES AVAILABILITY: ALL

These options specify that all sensors are supplied from a single process batch and lot of foil. They are primarily used to obtain the
closest possible matching of performance characteristics from a large group of gages.

SP11: One sensor type from a single batch of processed foil

SP12: Two sensor types from a single batch of processed foil

SP13: Three sensor types from a single batch of processed foil

SP14: Four sensor types from a single batch of processed foil

OPTIONS SP21, 22, 23, 24

SERIES AVAILABILITY: EK, WK, SK, S2K

This option series provides strain gages with ‘Modulus Compensation’ features through use of specially modified lots of K alloy.
The ‘Mod-Comp’ match will be quite close for the materials specified, although thermal output characteristics may not be ideal.

When force-responsive type transducers are
manufactured from the metals listed, and the
appropriate Special Option gages are used, the result
is a transducer which demonstrates very little span
change with temperature.

OPTION SP30

SERIES AVAILABILITY: EA, WA, ED, WD, EK, WK, EP

General Description:

This option consists of special leadwires, either added to open-faced gages, or substituted for lead ribbons

on WA-, WK-, or WD-Series gages. The wire is very formable, and may be spot-welded or soldered to main leadwires. The primary
advantages are easy handling and excellent resistance to oxidation at the highest temperatures the gages can withstand.

Leads:

0.8 in (20 mm) long nickel-clad copper wires 0.005 in (0.13 mm) diameter. For some gage types, usually small patterns, wire
size must be reduced to 0.0035 in (0.09 mm) diameter.

Solder:

EA-, ED-, EK-, EP-Series gages: +430°F (+220°C) tin-silver alloy;

WA-Series gages: +570°F (+300°C) lead-tin-silver alloy; WK- and WD-Series gages: +770°F (+410°C) solder.

Temperature Limit:

E-backed gages: +400°F (+200°C); WA-Series gages: +500°F (+260°C); WKand WD-Series gages: +750°F (+400°C).

Fatigue Life:

Fatigue life will normally be degraded by Option SP30. This occurs primarily because the copper wire has limited cyclic endurance.
Option SP30 should therefore not be used when best fatigue life is required, unless the tab area of the gage is in a low strain area
(±1000μ

or less). Loss of cyclic endurance is experienced particularly with WA-, WK-, and WD-Series gages.

Size:

Matrix size

is unchanged. On W-backed gages, SP30 leads are substituted for the normal beryllium copper ribbon leads. One wire lead per
tab is supplied.

Strain Range:

Option SP30 normally reduces the strain range of E-backed gages but does not similarly affect

W-backed gages.

Flexibility:

E-backed gages with SP30 leads are not as conformable as standard gages. W-backed gages are

not affected.

Resistance Tolerance:

Not affected.

Optional Features—Stress Analysis Gages

Technical Data

OPTION SP60

SERIES AVAILABILITY: ONLY ON MANGANIN GAGES

SP60 is an encapsulation option available for L-backed manganin gages. The end of each tab includes a thin copper coating that
is left exposed for lead attachment.

OPTION SP61

SERIES AVAILABILITY: N2A, N2P

General Description:

This option provides conformable, soft copper lead ribbons and a 0.0005 in (0.013 mm) thick encapsulation

layer of polyimide film. The encapsulation layer provides excellent protection for the gage during handling and installation. It also
contributes greatly to environmental protection, though supplementary coatings are still recommended for field use. Gages with
Option SP61 will normally show better long-term stability than open-faced gages which are “waterproofed” only after installation. A
good part of the reason for this is that the encapsulation layer prevents contamination of the grid surface from fingerprints or other
agents during handling and installation. The presence of such contaminants will cause some loss in gage stability, even though the
gage is subsequently coated with protective compounds.

Leads:

0.010 wide x 0.002 in thick (0.25 x 0.05 mm) soft copper ribbons.

Leads are approximately 0.8 in (20 mm) long.

Solder:

+430°F (+220°C) tin-silver alloy. The solder is confined to small, well-defined

areas at the end of each ribbon.

Temperature Limit:

+400°F (+200°C).

Grid Protection:

Entire gage is encapsulated. A short

extension of the backing is left uncovered at the leadwire end to prevent contact between the leadwires and the specimen surface.

Size:

Matrix size is unchanged.

Strain Range:

Strain range will usually be reduced by the addition of Option SP61.

Flexibility:

Gages with Option SP61 are not as conformable as standard gages.

Resistance Tolerance:

Resistance tolerance is normally

doubled by the addition of Option SP61.
