Hysteretic magnetism removing method for magnetoelastic torque transducer sensor, involves exiting coil with alternating current of desired frequency and amplitude to selectively erase hysteretic magnetic field remanent

摘要

The method involves supporting a coil (22) concentrically relative to a magnetoelastic portion of the torque transducer (15) and exiting the coil with an alternating current (25) of desired frequency and amplitude to selectively erase the hysteretic magnetic field (18) remanent.
