KFGS
for Residual Stress Measurement

Summary
KFGS T-F7
KFGS 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.
KFGS-D28
Designed to measure residual stress released by the boring method.
