Test and Evaluation of Temperature Response of High-temperature Piezoelectric Acceleration Sensor
In view of the development demand that the existing high-temperature acceleration sensor needs to quantify the temperature response gap with similar imported products, a synchronous high-temperature vibration comparative test method of high-temperature acceleration sensor is proposed, and a special test system is developed. The test and evaluation of the temperature response and high-temperature stability of a certain type of high-temperature piezoelectric acceleration sensor and the same kind of imported products are carried out by comparison. The sensitivity of the piezoelectric acceleration sensor increases with the increase of temperature in the temperature range of 23-400 ℃.The maximum sensitivity temperature drift of the piezoelectric accelerometer is 6.17%, which is about 2.53 times of the Kistler accelerometer. In terms of high-temperature stability, the average high-temperature sensitivity stability of the piezoelectric accelerometer is about twice that of the Kistler accelerometer.
