热电偶检定系统中检定炉的温度控制及分析

Temperature Control and Analysis of Tested Furnace in Thermocouple Testing System

通过建立热电偶检定炉控温的物理模型,分析了影响热电偶检定炉温场均匀性和稳定性的因素,并进一步探讨了消除这些因素的方法,为提高热电偶检定炉测试的正确性和热电偶检定数据准确性提供一些参考。

By the establishment of physical model of thermocouple testing furnace, the factors affected temperature field evenness and stabilization of thermocouple testing furnace were analyzed, and the methods to eliminate the factors were discussed, which provided reference for improving the tested exactness of thermocouple testing furnace and thermocouple tested data accuracy.
