Design principle of integrated direct digital sensor of rotation rate and torque

Based on measuring technique of ordinary sensor of rotation rate and torque, this article mainly studied the sensing element of CMF (Coriolis Mass-Flow Meter), and designed for the prototype an IDDSRT (Integrated Direct Digital Sensor of Rotation Rate and Torque) that consists of torsion-bar spring, measuring fluted disc, and photoelectric sensing device. The sensor measures with high-frequency pulse. This design reduces the factors that affect the measuring, completely realizes non-contact digital measurement, greatly improves the anti-jamming ability and the measuring stability, and therefore increases measuring accuracy.
