Japan, Kyowa Electronic Instruments Co., Ltd.
Kyowa KCH 350Ω Bridge, for shearing KCH Series Foil Strain Gages with a Protector
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
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.
