Kyowa KFB120Ω single axis for Foil strain gauge for axial force of KFB bolts
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
If it is difficult to attach a gauge to the surface of the bolt, such as when measuring the tightening stress of a bolt, it is possible to measure by drilling a φ2 hole in the “top of the head” and embedding this gauge.
