Abstract—This paper presents wireless clamp-on torque transducer based on twist angle deformation measurement system using strain gauges. Firstly, the model of a torque measurement system based on the twist angle with strain gauges sensing structure is studied and developed. Secondly, for the system verification, the proposed model is presented as a case study. In this study, both the mechanical and electronics designs are discussed and analyzed. Particularly, using finite element analysis technique the mechanical sensitivity and maximum stresses of the torque sensor are examined. While the readout electronics of the system is verified experimentally by laboratory tests. The torque sensor has the capability of ±50Nm with 0.023 V/Nm of sensitivity under static torque measurement. Finally, the performance of the developed scheme is examined by carrying out simulations followed by experiments.
