For stress measurement of reinforcing bar
The BF-CT series stress transducers are designed for stress measurement by welding both ends to a reinforcing bar in the field. They are available in various models for selection according to diameters of the reinforcing bars. 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 the temperature stress of the reinforcing bar.
