RVDT data acquisition system is widely used in the flight control system research and testing for the field of civil aviation. RVDT transforms the mechanical displacement signal into electrical signal. Data acquisition system receives the differential signal which is exported from RVDT,then displays the signal after being transformed and calculated. The calibration method for RVDT data acquisition system based on AD598 is discussed,then uncertainty source and analysis method are introduced.
