【発明の名称】圧力補正型差圧センサと方法
Document Type and Number:
Japanese Patent JPS61501654
Kind Code:
A
Abstract:
A differential pressure sensor (10) senses a difference in pressure between a first input (low) pressure (12) or "reference pressure" and a second input (high) pressure (14) and provides a differential sensor signal representative of the difference in pressure. The reference pressure is sensed by a reference pressure sensor (26) which provides a reference signal representative of the reference pressure. The differential sensor signal and the reference signal are provided to a correction circuit. The correction circuit (24), which is preferably a digital computer, adjusts the reference signal and provides an improved output signal as a function of the differential sensor signal and the adjusted reference signal.
