RVDT angle displacement sensors were used in athodyd engine for measuring fuel regulator opening angle and fuel flow. Comparing with the set flow,feedback was achieved to reach the purpose of fuel flow rate adjusted accurately with engine state changing. The application background,present situation and working principle of RVDT sensor were introduced in this paper. Calibration method and related experimental research of RVDT sensor and signal conditioning circuit were analyzed emphasizely. The matching characteristic test of RVDT sensor and signal conditioning circuit was progressed,showing that the signal conditioning circuit was designed reasonably and reliably. Experimental research was carried out about the effect of the amplitude and frequency incentive on RVDT sensor. The research showed that amplitude excitation influenced on the sensor output largely. And the frequency excitation influenced on the output of the sensor a little. Using the calibration device,the measurement and calibration services were firstly provided for RVDT sensor and signal conditioning circuit of the athodyd engine. The measurement guarantee was provided for model task.
