摘要

在光纤光栅应变传感器性能测试及关键参数标定校准中,为了准确测量环境温度值,控制环境温场稳定、均匀,提高光纤光栅应变传感器测试准确性,设计了采用标准铂电阻和多路优良热电偶实现空间多点的温场测量方法;通过20℃时温度变化3℃范围内热电偶标定实验和系统的测量不确定度分析,得到整个系统实际测量不确定度在5mK以内,满足光纤光栅应变传感器的测试需求。

Abstract

In order to accurately measure the ambient temperature value, control the ambient temperature field to be stable and uniform, and improve the test accuracy of the fiber grating strain sensor, the standard platinum resistance and multi-channel excellent thermocouple were designed in the performance test of fiber grating strain sensor and the calibration of key parameters. To realize the multi-point temperature field measurement method, the thermocouple calibration experiment and the system measurement uncertainty analysis in the temperature range of 3 °C at 20 °C were carried out, the actual measurement uncertainty of the whole system was within 5mK, which can meet the testing needs of fiber grating strain sensors.
