BFD-A-TS
Reinforcing-bar Stress Transducer

BFD-A-TS

Summary

For stress measurement of reinforcing bar
The BFD-A-TS series transducers are designed for stress measurement of reinforcing bars whose nominal diameters are larger than those measured by the BF-CT series. The BFD-A-TS series is used by welding both ends to a reinforcing bar in the field. Select the model suitable for the diameter of the reinforcing bar. Each model provides a temperature measuring function to enable simultaneous measurement of stress and temperature.

Features

●For long-term stable measurement, the transducer proper features a special structure with inert gas filled in.
●The self-temperature-compensated strain gage used for the transducer enables measurement of temperature stress of the reinforcing bar.
