摘要
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 the paper,based on the circuit theory,the sensitivity of thermal resistance are analysed in the heat-sensitive sensor circuit, and then the influence of thermal resistance upon measurement sensitivity is discussed.At last, high-accuracy temperature measurement method which is satisfied with environment is reached.
