Abstract
A non-contacting torque sensor is provided for measuring the torque of stationary and slowly rotating shafts. The torque sensor employs an oscillating thin-wall cylinder to produce a signal whose frequency is directly proportional to the torque applied to a shaft. Electromagnetic coils drive the cylinder at its natural frequency and sense its motion to produce a signal that is proportional to torque. Temperature and shaft bending effects are minimized by accordion folds integrally formed at the end portions of the oscillating cylinder.
