Abstract
A system for indicating torque and/or speed of a rotatable shaft includes a transducer positioned adjacent the shaft. The transducer has two primary windings wound in a bifilar arrangement on the same magnetic core structure. The primary windings are connected in a manner to facilitate driving of the transducer primary windings with a simple switching circuit.
