BFD-A-TS
300 MPa
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.

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 |
