摘要
温度传感器自动检测系统主要通过被测件与标准器的实时比对,实现对传感器的精确测量,而系统的误差分析则是保证测试精度的关键.介绍了温度传感器自动检测系统的组成及测试方法,并且通过对一只温度传感器的实测,详细分析了影响该系统测试精度的几种误差来源,同时对各个误差的不确定度进行了分析和评定,最后给出了整个系统的总不确定度.
By the real-time contrast with the tested pieces and standard equipment, the automatic test system for temperature sensor can realize the sensor exact testing, and the analysis of system error is key to guaran- tee test precision. The automatic test system for temperature sensor composition and the testing method are in- troduced while several error sources affecting test precision are analyzed by testing a temperature sensor. The uncertainty of each system error is analyzed and evaluated. Finally the uncertainty of the whole system is given.
