■Strain, Stress, and Poisson's RatioWhen tensile force P is applied to a material, it has stress σ that corresponds to the applied force. In proportion to the stress, the cross section contracts and the length elongates by ΔL from the length L the material had before receiving the tensile force (See the upper illustration in Fig. 1.) below.

The ratio of the elongation to the original length is called a tensile strain and is expressed as follows:

See the lower illustration in Fig. 1. If the material receives compressive force, it bears compressive strain expressed as follows:

For example, if tensile force makes 100 mm long material elongate by 0.01 mm, the strain initiated in the material is as follows:

Thus, strain is an absolute number and is expressed with a numeric value with x10-6 strain, με or μm/m suffixed.Based on Hooke's law, the relation between stress and the strain initiated in a material by the applied force is expressed as follows:

Stress is thus obtained by multiplying strain by the Young's modulus. When a material receives tensile force P, it elongates in the axial direction while contracting in the transverse direction. Elongation in the axial direction is called longitudinal strain and contraction in the transverse direction, transverse strain. The absolute value of the ratio between the longitudinal strain and transverse strain is called Poisson's ratio, which is expressed as follows:

Poisson's ratio differs depending on the material. For major industrial materials and their mechanical properties including Poisson's ratio, see page 9-1.

■Principles of Strain Gages ■Types of Strain Gages

■Structure of a Strain Gage

If external tensile force or compressive force increases or decreases, the resistance proportionally increases or decreases. Suppose that original resistance R changes by ΔR because of strain ε: the following equation is set up.

Where, Ks is a gage factor, expressing the sensitivity coefficient of strain gages. General-purpose strain gages use copper-nickel or nickel-chrome alloy for the resistive elements, and the gage factor provided by these alloys is approximately 2.

Types of strain gages are classified into foil strain gages, wire strain gages, and semiconductor strain gages, etc.

The foil strain gage has metal foil on the electric insulator of the thin resin, and gage leads attached, as shown in Fig. 2 below.The strain gage is bonded to the measuring object with a dedicated adhesive. Strain occurring on the measuring site is transferred to the strain sensing element via adhesive and the resin base. For accurate measurement, the strain gage and adhesive should be compatible with the measuring material and operating conditions such as temperature, etc.

A strain gage detects a minute dimensional change (strain) as an electric signal. By measuring strain with the gage bonded to a material or structure, the strength or safety will be known. Thus, the strain gage is used in various industries including machinery, automobile, electric, civil engineering, medical, and food.The strain gage is also adopted as a sensing element of force, pressure, acceleration, vibration, displacement, and torque transducers used for various purposes including measurement and control of production lines.Kyowa produced the first Japanese-made strain gages in 1951, and based on the abundant experience and technology accumulated for these years, we manufacture a variety of high-performance, environmentally friendly strain gages.

■Principles of Strain Measurement

■Strain Gage Wiring System

Strain-initiated resistance change is extremely small. Thus, for strain measurement a Wheatstone bridge is formed to convert the resistance change to a voltage change. Suppose in Fig. 3 resistances (Ω) are R1, R2, R3 and R4 and the excitation voltage (V) is E. Then, the output voltage eo (V) is obtained by the following equation:

Suppose the resistance R1 is a strain gage and it changes by ΔR due to strain. Then, the output voltage is,

If R1 = R2 = R3 = R4 = R in the initial condition,

Since R may be regarded extremely larger than ΔR ,

Thus obtained is an output voltage that is proportional to a change in resistance, i.e. a change in strain. This microscopic output voltage is amplified for analog recording or digital indication for strain measurement.

A strain gage Wheatstone bridge is configured with a quarter, half, or full bridge according to the measuring purpose. The typical wiring systems are shown in Figs. 4, 5 and 6. For various strain gage bridge systems, see pages 9-7 and 9-8.●Quarter-bridge system (1-gage system)With the quarter-bridge system, a strain gage is connected to one leg of the bridge and a fixed resistor is connected to each of the other 3 legs. This system will be easily configured, and thus it is widely used for general stress or strain measurement. The quarter-bridge 2-wire system shown in Fig. 4-1 is largely affected by leads. Therefore, if a big temperature change is expected or if the lead-wire length is long, then the quarter-bridge 3-wire system shown in Fig. 4-2 must be used. For the quarter-bridge 3-wire system, See "Compensation Methods of Temperature Effect of Lead Wires" (See page 9-4).

●Half-bridge system (2-gage system)With the Half-bridge system, 2 strain gages are connected to the bridge, one each to adjacent or opposite legs with fixed resistors inserted in the other legs. See Figs. 5-1 and 5-2. There is the active-dummy system, where one strain gage serves as a dummy gage for temperature compensation, and the active-active system, where both gages serve as active gages. The half-bridge system is used to eliminate strain components other than the target strain; according to the measuring purpose, 2 gages are connected to the bridge in different ways. For details, See "How to Form Strain-gage Bridge Circuits" (See pages 9-7 and 9-8).

●Full-bridge system (4-gage system)See Fig. 6. The full-bridge system has 4 strain gages connected one each to all 4 legs of the bridge. This circuit ensures large output of strain-gage transducers, improves temperature compensation and eliminates strain components other than the target strain. For details, see "How to Form Strain-gage Bridge Circuits" (See pages 9-7 and 9-8).

■Self-temperature-compensation Gages (SELCOM Gages)

■The following are described 　in Technical Memo. (See the chapter 9.)When receiving a temperature change, a strain gage

bonded to a measuring object generates an apparent strain due to a difference in linear expansion coefficient between the measuring object and the resistive element of the strain gage, and a thermally-induced resistance change of the gage element. The SELCOM gage has a resistance temperature coefficient of the resistive element adjusted to match with the measuring object, thereby minimizing the apparent strain.Kyowa's SELCOM gages have been adjusted so that, when they are bonded to suitable measured materials, the average value of the apparent strain in the self-temperature-compensation range is within ±1.8 μm/m per °C* (representative value).As shown in Fig. 7, the thermally-induced apparent strain of KFGS gages is within ±1 μm/m per °C* in a temperature range of 20 to 40°C in which they are most frequently used. For the principle of SELCOM gages, see page 9-4. For the models and suitable measured materials, see page 1-6.

For the types of lead-wire cables, see pages 1-15 and 1-16.

●General-purpose Foil Strain Gages KFGS

The KFGS series gages use polyimide resin for the base that is approx. 13 μm thick. It ensures excellent flexibility. The outstanding moisture proof enables the KFGS gages to operate e�ectively both indoors and outdoors. Unless directly exposed to water droplets, no coating treatment is required.

■Types, lengths and codes of lead-wire cables pre-attached to KFGS series gages

Notes on pre-attached lead-wire cables ●Standard color of the 2-wire cable pre-attached to uniaxial gages is red (R). 　If desired, allows a white, green, yellow or black cable to be pre-attached. ●Standard stripe of the 3-wire cable pre-attached to uniaxial gages is a red stripe. 　If desired, allows a blue or yellow stripe to be pre-attached. ●In the case of a biaxial gage and triaxial gage, 2-wire cables are color-coded 　with red, white and green stripes for 0°, 90° and 45°, respectively and 3-wire 　cables, with red, yellow and blue stripes for 0°, 90° and 45°, respectively. 　The letter code is S in common.

When ordering, specify the model of the strain gage and the code of the lead-wire cable with a space in between.

If no lead-wire cable code is su�xed, the gage is delivered with gage leads only. (Silver-covered copper wires 25 mm long)

●KFGT Series Foil Strain Gages with a Temperature Sensor The KFGT gages are foil strain gages incorporating a T-type thermocouple for simultaneous measurement of strain and temperature. They ensure e�cient strain measurement under environments where temperature change or temperature gradient requires simultaneous measurement of strain and temperature. They also provide highly precise compensation of thermally-induced apparent strain. It is recommended to use Kyowa data logger UCAM-60C M14 as a measuring instrument.

The surface of the KFWB series foil strain gage is covered with a special waterproof resin. The waterproof structure enables these gages to serve for outdoor or underwater measurement merely by being bonded to measuring objects. (The insulation resistance shows virtually no deterioration even after 100 hours of use under an underwater pressure of approximately 10 MPa.) In addition, the covering resin is flexible enough to enable easy bonding to curved surfaces.

The following models are delivered with a vinyl-coated flat 3-wire cable 1 m long pre-attached.

●KM Series Embedded Strain Gages

●KMC Series Concrete-embedded Strain Gages

Operating Temperature: Normal temperature to 70°C

Operating Temperature: –10 to 70°C

The KM series gages are designed to be embedded in mortar or concrete for the purpose of measuring the internal stress. To ensure better adhesion to mortar or the like, the KM series gages feature a specially treated surface. They also provide suitable waterproofness and elastic modulus for the intended purpose.

The KMC series gages are designed to measure self-shrinkage and self-stress of cemented materials. They enable measurement of the self-shrinkage and high-fluidity concrete immediately after placing. They are also used e�ectively to check for cracks of cemented materials. Usually, a T-type thermocouple is installed near the gage, while the KMC series gages of H4 type do not require such the installation since they are equipped with a built-in thermocouple.


The KMC series gages are available only with a vinyl-coated flat 3-wire cable 3 m long pre-attached.

●KFRPB Series Foil Strain Gages for Composite Materials

The KFRPB series foil strain gages are self-temperature-compensation gages (SELCOM gages) suitable for strain measurement of composite materials such as CFRP and GFRP. The special gage pattern minimizes the e�ect of self-heating due to gage current and the e�ect of reinforcement of low-elasticity materials.To ensure accurate measurement by avoiding the self-heating e�ect of gage current, consider the following:

1. Select a lower excitation voltage on a measuring instrument.2. Active-dummy system3. 350Ω strain gages

●KFEL Series High-elongation Foil Strain GagesDeveloped to measure strain from elastic to plastic region on structures, the KFEL series foil gages allow the strain to be measured as large as 10% to 15% with simple tension strain.

Note: Besides the usual surface treatment with sandpaper, the gage bonding surface should be treated with the surface treatment agent S-9B if the gage is bonded to non-adhesive plastics such as polyethylene and polypropylene. Then, bond the gage using the adhesive CC-36. For S-9B and bonding conditions for other special materials, contact us.


●KFEM Series Ultrahigh-elongation Foil Strain GagesKFEM series ultrahigh-elongation foil gages allow strain to be measured on various regions of structures, from elastic to plastic, and are suitable for large strain measurement. They can measure 20 to 30% of material deformation.

●KFSB Series Shielded Foil Strain Gages

The KFSB series foil strain gages are shielded by copper foil covering the whole body. Thus, if a large current flows to or around the gage bonding site, noise will be prevented from entering the measuring circuit.

●KFNB Series Non-inductive Foil Strain Gages

The gage element is made of a special alloy which provides less magnetoresistant e�ect; also, the shape is designed to eliminate induction. Thus, the KFNB series foil strain gages allow the strain to be measured accurately under AC magnetic environments.

KFV-2-350-C1

●KFV Foil Strain Gage for Hydrogen Gas EnvironmentKFV is a foil strain gage that enables stable strain measurement under high-pressure hydrogen gas environments. The metal foil of conventional foil strain gages has the electric resistance changed by receiving hydrogen e�ect, thereby disabling stable strain measurement. KFV strain gage receives less electric resistance change due to hydrogen, thereby enabling stable strain measurement.

●KFF Series Foil Strain Gages for Bending Strain MeasurementThe KFF series foil strain gages have one each sensing element on both the upper and lower sides of the thick plastic base. If measuring stress in box structures such as bridge girders, or in high-pressure vessels that do not allow gages to be bonded directly to the inside of the measuring object, the KFF series gages can be bonded to the outside surface to obtain strain on the inside.

●When using this gage, use it properly according to the thickness of the object being measured.●When the object being measured is thin (approx. 1 mm or less), the sensitivity

drops due to the impact of the reinforcement e�ect caused by gage contact. When the measurement object is thick (approx. 30 mm or more), the accuracy deteriorates.[Examples of proper gage models for the thickness of measurement objects]KFF-30-350-C11: Approx. 1 mm to 15 mmKFF-30-350-C12: Approx. 4 mm to 30 mm

The unique design simplifies gage bonding, wiring and moisture-proofing work in the field. In addition, the metal case protects the strain gage and significantly improves reliability compared with conventional gages. Using stud bolts and adhesive allows the gages to be mounted to the bottom or side plate of a tank for strain measurement, to a hopper or tank for weight measurement, to the shaft of a truck for tare weight measurement or any other similar applications where the gages need to be protected against moisture, water or small stones.

To obtain good measurement results, the strain gage must be bonded firmly to the measuring object. Thus, it is important to select an adhesive suitable for the materials of both the object being measured and the gage base, as well as for the measuring conditions.

Note: The stated operating temperature range is for the adhesive only, and may di�er depending on combinations with gages. When using the adhesives and gages together, read the attached instruction manual carefully.

*1 Place it in a heating furnace or the like, and perform aging according to the following requirement. (A temperature increasing speed should be about 5°C/minute.) KFU gage: Increase heating temperature from room temperature to 300°C,then maintain 300°C for 2 hours. KFHB gage: Increase heating temperature from room temperature to 250°C,then maintain 250°C for 2 hours.

Being excellent in nonlinearity & repeatability, strain gages can be used not only to test strain, but to make transducers as well.We use our own strain gages to produce our strain gage transducers, so naturally the transducers are of high reliability.

We provide various strain gages for our customers to make their own transducers to test load, force, pressure, torque, etc.The following patterns are some examples.For details, please contact us.
