摘要
提出一种利用集成温度传感器ＡＤ５９０对热电偶进行冷端温度补偿的方法，在使用中，只需将热电偶的冷端与集成温度传感器ＡＤ５９０置于同一环境中，不论环境温度如何变化，均可在电路的输出端得到正比于热电偶工作端温度的电压值。
A method of using IC temperature transdueer AD590 to compensate the cold ter-minal temperature for thermocouple is presented. In application,the cold terminal and the ICneed be put into the same environment only,a voltage which is proportional to the work term-inal temperature of the thermocouple is obtained at the output of the circuit, whatever thetemperature in the environment is varied.
