    摘要： An axially extending annular metal ring having a plurality of spaced slots is attached to a rotating disk. A driven magnetic inductor is placed on one side of the ring and a pick-up inductor is placed on the other side of the ring and opposite the driven inductor for the emission of output signals each time one of the slots comes into alignment with the two inductors. The output signals are transformed into digital pulses which coincide with the alignment of the center of the slot with the two inductors. The pulses, together with a reference or index signal that is generated during each revolution of the ring, are used to determine the relative position of the rotating member.
