摘要
针对现有高温加速度传感器需要量化与同类进口产品的温度响应差距的开发需求, 提出了一种高温加速度传感器的同步高温振动对比测试方法, 并开发了专用测试系统, 对比开展了某型号高温压电加速度传感器与同类进口产品的温变响应和高温稳定性测试评价。在23~400 ℃升温段内, 该压电加速度传感器的灵敏度随着温度升高均呈现增大的基本趋势, 最大灵敏度温度漂移量为6.17%, 约为Kistler传感器的2.53倍; 在高温稳定性方面, 该压电加速度传感器的高温灵敏度稳定度均值约为Kistler传感器的2倍。
Abstract
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.
