日本的共和电业公司研制成功用于测量发动机、电机等转轴的扭转力矩的非接触式新型扭矩传感器。这种扭矩传感器的特点是,在转轴上贴上应变片,将应变片上取得的输出电压通过变压器传出去。原来采用滑环的应变片式扭矩传感器,虽然其精度和稳定性方面均较高。但是,由于有滑动摩 Japan’s Republican Electric Company successfully developed a new non-contact torque sensor for measuring the torque of the engine, motor shaft rotation. This torque sensor is characterized by the shaft attached to the strain gauge, the strain gauge obtained by the output voltage transmitted through the transformer. The original use of slip ring strain gauge torque sensor, although its accuracy and stability are higher. However, due to sliding friction
