Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: BR-100KBT

Enables measure concrete stress directly as stress and not via strain.
A temperature measuring function enable them to measure stress and temperature simultaneously.

Features

●Theoretically backed performance of direct concrete stress measurement with no conversion from a detected strain quantity.
●Receive minimal effects of creep and changing elastic modulus of concrete. and there by ensure accurate stress measurement.
●Also usable for stress measurement of the natural ground by installing at the rear of a tunnel lining.
