Portable on-site calibration device for torque transducer

摘要

According to the material mechanics, when the shaft has torsion, it produces a deflection angle which is directly proportional to the torque. The torque transducer installed in the measured shaft has a tiny displacement with the shaft's torsion. Thus, we designed a torque calibrator which can produce tiny displacement to simulate the torsion of the shaft, and compared the signal of the transducer installed in the shaft with that of the standard transducer at the work site. The specialty of the calibrator is: we can complete the calibration only by installing the transducer which will be calibrated and the standard transducer in the calibrator, without additional loading.
