摘　　要：热电偶是一种由2种导体组成并将温度转化为热电动势的传感器设备。介绍了热电偶温差电势实验仪的工作原理、设计思想以及低温端测量原理和高温端测温控温原理的电子线路实现。本仪器具有安全、自动控温、超温保护、对电网的干扰小等优点。The thermocouple is a sensor equipment which is composed of two conductor and can translate the temperature into electromotive force. This paper introduced the measuring principle of thermocouple and the design idea for the equipment, as well as the realization of electric circuit for the principle of measuring temperature for low-temperature and the temperature measuring and controlling for high-temperature. The instrument has many advantages such as safety, auto temperature-controlling, temperature protection and small-disturbance etc.
