ABSTRACT:
A position measurement device using a variable differential transducer. The primary of the transducer is supplied with a triangular pulse causing a similar pulse to be produced at the transducer secondary. The induced pulse is then compared with a constant reference voltage. Due to the triangular shape of the induced pulse, the time that the induced pulse is greater than the reference voltage is indicative of the magnitude of that pulse. The time period is then counted and communicated to subsequent devices.
