MEASUREMENT AND CONTROL OF MAGNETOSTRICTIVE TRANSDUCER MOTION ABSTRACT OF THE DISCLOSURE Apparatus and method for precisely controlling the movement of a magnetostrictive transducer including an elongated magnetostrictive rod, means for inducing a magnetic field in the rod and supplying drive current for moving the rod in response to the drive current. A temperature compensated strain sensor configuration on the rod detects the amount of rod movement in response to the drive current and provides an output signal proportionate thereto. Feedback control means coupled between the strain sensor and the current driver respond to the strain sensor output signal and vary the drive current until the strain sensor output signal matches the voltage reference set point developing the drive current.
