ABSTRACT:
A position sensor comprising a movable member functionally connected with an operative device and moving in response to a positional displacement of the operative device, a displacement-pulse phase conversion unit including a magnetically soft amorphous metal member undergoing stress variations produced by the displacement of the movable member and an electrical coil wound on the magnetically soft amorphous metal member. A pulse voltage is applied to one end of the electrical coil, the other end of which is connected in series with a resistor. A voltage across the resistor is detected, and a time lag of the resistor voltage with respect to the pulse voltage, representing a measure of displacement, is provided in the form of an analog voltage or a digital code.
