Kyowa KFF350Ωsingle axis Foil strain gauge for KFF bending strain
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
A gauge that has sensing elements on both the top and bottom sides of a thick plastic base, and is used when measuring stress due to internal pressure in a high-pressure vessel, etc., or when measuring stress in a box structure such as a bridge girder, where the gauge cannot be attached directly to the back of the specimen. , you can determine the strain on the back side by sticking it on the surface.
