OUTPUT CORRECTION METHOD FOR PRESSURE SENSOR AND OUTPUT CORRECTION DEVICE FOR PRESSURE SENSOR

摘要

PROBLEM TO BE SOLVED: To provide an output correction method for pressure sensors and an output correction device for the pressure sensors designed so that when a pressure sensors is changed, output values of the sensor is smoothly replaced without drastically changing them.;SOLUTION: The output correction device includes a plurality of pressure sensors having mutually different measurement ranges, and when an output of a No. 1 sensor reaches a predetermined sensor changing pressure, the No. 1 sensor is changed to the other sensor, and an average shifting value is output in place of the output value of the other sensor, by obtaining a pressure gradient at the time when the No. 1 sensor is changed and by setting an average shifting number N according to the pressure gradient.;COPYRIGHT: (C)2009,JPO&INPIT
