Abstract  For the problem that the sensitivity of the piezoelectric acceleration sensor increases with the increase of temperature in a high temperature environment,a sine-approximation absolute calibration method for the acceleration sensor is proposed and a related experimental system is built.The sensitivity measurement and calibration test of the high temperature resistant acceleration sensor are carried out by the mentioned method under different temperature environments from room temperature to 400℃.The experimental results show that the sensitivity of the acceleration sensor shows a linear increase trend when the ambient temperature rises.
