KFB series
Strain Gages for Measuring Axial Tension of Bolts


The KFRPB series foil strain gages are self-temperature-compensation gages (SELCOM gages) suitable for strain measurement of composite materials such as CFRP and GFRP.



If it is difficult to bond a strain gage to the surface of a bolt for measuring the tightening stress, these gages enable the measurement by embedding into a hole, 2 mm in diameter, bored from the top head of the bolt.
