一、热敏电阻测温标定由于热敏电阻特性分散,每个热敏电阻需逐个标定,即每个热敏电阻需分别标出25℃和85℃时的阻值,由关系式:标出材料常数B。式中RT_1、RT_0是与温度T_1、T_0对应的热敏电阻阻值;T_1、T_0是标定温度。其他各温度点的阻值用关系式:
First, the thermistor temperature calibration As the thermistor characteristics of dispersion, each thermistor to be calibrated one by one, that is, each thermistor shall be marked separately at 25 ℃ and 85 ℃ when the resistance, by the relationship: marked Material constant B. Where RT_1, RT_0 is the temperature of the thermistor T_1, T_0 corresponding resistance; T_1, T_0 is the calibration temperature. The resistance of other temperature points with the relationship:
