BFD-A-TS

Reinforcing-Bar Stress Transducers

300 MPa

BFD-A-TS

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.

Calibration

 

 

 

The BFD-A-51TS is calibrated by applying to a single
sensing section, compressive load (approx. 600 kN) equivalent to the
rated capacity of 300 MPa and compressive load (approx. 670 kN)
equivalent to the safe overload rating
