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.
?? 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 |
