摘要
文章从理论上对温控电路中热敏电阻构成的桥路灵敏度进行了分析,探讨了热敏电阻属性对测量灵敏度的影响,得出了满足环境要求的高精度温度测量方法.
In this paper, based on the circuit theory, the sensitivity of bridge circuit formed by the thermistance have been analyzed in the temperature control circuit. The influence of thermistance upon measurement sensitivity has been discussed. The high accuracy temperature measurement method which is satisfied with environment has been reached.
