Design of Automatic Calibration System for Aeroengine Airborne Pressure Measurement Instruments

The automatic calibration system design of the aeroengine pressure measurement instruments was introduced.The automatic field calibration of airborne pressure measurement instruments was realized by the system which has been successfully adopted for the automatic calibration operation of an aeroengine airborne pressure measurement instruments.The testing and calibration accuracy reached to 0.01 % FS under 0~7 MPa(gauge pressure,absolute pressure).
