COMPACT DIGITAL PRESSURE SENSOR CIRCUITRY

Abstract

A conditioning circuit for use with a pressure transducer is disclosed which provides a digitally readable electronic output signal indicative of capacitance sensed by the pressure transducer. The circuitry of the present invention utilizes an R-C charge/discharge circuit, thereby enabling the circuitry to be substantially more compact than previously utilized L-C circuits. The circuitry is usable with either pressure transducers having a single capacitance or those including a reference capacitance, and the circuitry provides a high resolution, high precision output.
