热电偶配电位差计测温系统的冷端处理
Cold end treatment of thermocouple potentiometer temperature measuring system
本文分析了热电偶配电位差计测温系统冷端补偿导线及电阻的作用，热电偶的热电势不仅与工作端温度有关，还与参比端有关，只有固定参比端温度才能通过热电势的大小来判断热点温度的高低。若参比端温度波动较大，就需要使用补偿导线将冷端延长到一个温度相对稳定的地方，然后处理冷端。
This paper analyze the role of code end Compensation wire and resistance of thermocouple potenticmeter temperature measuring system.The thermoelectric potential of thermocouple is not only related to the temperature of walking end, but also related to the reference end. Only the temperature of fixed refrence end can judge the temperature of hot spot though the size of the thermoelectric potential .If the reference end temperature Fluctuation is large, it's necessary to use the Compensation wire to extend the cold end to a place where the temperature is relatively stable and then deal with the cold end. Some more couple partion meter Temperature measurement system code and Treatment
