Strain Gages
- KFGSGeneral-purpose Foil Strain GagesNew strain gages with the world highest level performance.
- KCWire Strain GagesFeaturing a longer gage length, the KC series gages are wire strain gages suitable for mean strain measurement of concrete under test. Usually, a model with the gage length over 3 times longer than the maximum diameter of the aggregate (gravel, sand, etc.) is selected for the purpose.
- KCHFoil Strain Gages with a ProtectorThe 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.
- KCWWeldable Waterproof Foil Strain GagesThe KCW series foil strain gages are weldable gages, which do not require any coating treatment for use under high pressure or under water. The G10 type endures a water pressure of approximately 10 MPa.
- KFBStrain Gages for Measuring Axial Tension of BoltsIf it is difficult to bond a strain gage to the surface of a bolt for measuring the tightening stress, these gages enable the measurement by embedding into a hole, 2 mm in diameter, bored from the top head of the bolt.
- KFELHigh-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.
- KFEMUltrahigh-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. *Strain limit of 20% to 30% is ensured for simple tension applied to the gage bonded on stainless steel (SUS 304) or aluminum alloy (A1050) at normal temperature.
- KFGSfor Residual Stress MeasurementKFGS gages equipped with a gage terminal enable one-touch- connection/disconnection of the lead-wire cable. They are suitable for residual stress measurement with the cutting method. A clip-equipped dedicated cable T-C26 (Vinyl-coated, 2 m long) is optionally available.
- KFFFoil 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.
- KFGSfor ConcreteListed here are the KFGS series gages with a suitable lead-wire cable for strain measurement of concrete.
- KFGSfor Boring MethodDesigned to measure residual stress released by the boring method.
- KFGTFoil Strain Gages with a Temperature SensorThe KFGT gages are foil strain gages incorporating a T-type thermocouple for simultaneous measurement of strain and temperature. They ensure efficient 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-80A as a measuring instrument.
- KFHBHigh-temperature Foil Strain Gages (250ºC)The base is made of highly heat-resistant polyimide and the gage element is made of NiCr alloy foil, thereby ensuring less thermal output and excellent temperature characteristics.
- KFLBLow-temperature Foil Strain GagesThe gage element is made of NiCr alloy, which exhibits excellent characteristics under low-temperature environments and is sandwiched between polyimde films. Thus, the KFLB series gages are suitable for strain measurement of tanks and vessels containing low-temperature liquids such as LNG and LPG.
- KFNBNon-inductive Foil Strain GagesThe gage element is made of a special alloy which provides less magnetoresistant effect; 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.
- KFPFoil Strain Gages for PlasticsThe KFP series foil strain gages provide an applicable linear expansion coefficient of 65 x 10 ⁻⁶ /ºC, which makes them suitable for strain measurement of plastics such as acrylic resin.
- KFRBGeneral-purpose Foil Strain GagesThe KFRB series foil strain gages are durable and easy-to-use high-grade strain gages. The gage element is sandwiched between heat-resistant polyimide base and cover, thereby letting it exhibit high performance in a wide temperature range.
- KFRPBFoil Strain Gages for Composite MaterialsThe 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 effect of self-heating due to gage current and the effect of reinforcement of low-elasticity materials. To ensure accurate measurement by avoiding the self-heating effect of gage current, consider the following: 1. Select a lower excitation voltage on a measuring instrument. 2. Active-dummy system 3. 350Ω strain gages
- KFRSFoil Strain Gages for Printed BoardsPCB are used for varieties of products including cellular phones, car navigation systems and digital cameras. The gages are the self-temperature-compensation gages (SELCOM gages) for evaluating them.
- KFSBShielded Foil Strain GagesThe 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.
