Japan, Kyowa Electronic Instruments Co., Ltd.
Kyowa KV-5C, KV-25B KV crack gauge
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Features
●Crack propagation and propagation velocity can be electrically obtained
●Can be used on both flat and curved surfaces
●Crack length and resistance change become almost linear
●Using an adapter allows the use of conventional strain gauges
●Conventional optics It is very simple compared to conventional methods
. There are two trigger lines before and after the grid, which can be used for automated measurement (KV-5C).
