CALIBRATION SYSTEM FOR DIFFERENTIAL PRESSURE MEASURING INSTRUMENT AND CALIBRATION METHOD OF DIFFERENTIAL PRESSURE MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a calibration system for differential pressure measuring instrument in which a differential pressure measuring instrument can be calibrated efficiently.;SOLUTION: A calibration system 40 for a differential pressure measuring instrument 3 is provided. The calibration system for the differential pressure measuring instrument comprises a collection circuit 41, a first correction expression determination section 45a and a second correction expression determination section 45b. The collection circuit 41 collects a plurality of detection values of pressure detected by a first pressure measuring instrument 1 to which pressure of a plurality of setting values has been applied by a pressure generating device 4 and a plurality of detection values of pressure detected by a second pressure measuring instrument 2 to which pressure of a plurality of setting values has been applied by the pressure generating device 4. The first correction expression determination section 45a determines a first correction expression for the detection value of the pressure detected by the first pressure measuring instrument 1 on the basis of a difference between the plurality of setting values and the plurality of detection values detected by the first pressure measuring instrument 1. The second correction expression determination section 45b determines a second correction expression for the detection value of the pressure detected by the second pressure measuring instrument on the basis of a difference between the plurality of setting values and the plurality of detection values detected by the second pressure measuring instrument 2.;COPYRIGHT: (C)2013,JPO&INPIT
