热电偶冷端温度补偿器的研制

The Study and Made of Temperature Compensator of the Clod Side of The Thermocouples

在温差电偶实验中 ,要保持冷端温度恒定 ,通常是将其冷端置于冰水混和物中。这种方法需要制冰 ,实验准备复杂 ,且效果也不很理想。对实验进行改进 ,制作一台冷端温度补偿器 ,用其取代冰水混和物。实践证明 ,补偿器工作稳定 ,补偿准确 ,迅速 ,效果良好。

On the thermocouple test, the clod spot of the thermocouple must be stable. Mostly, the clod spot is put into the mixture of water and ice. The ice must be made by us. the preparing working is complex and the result is not satisfying. For improving this experiment, a temperature compensator is made out, which replaces the mixture of water and ice .The practice proves that the working of the compensator is stable, the compensating action is accurate and quick, the effect is very good.
