本文在所述负温度系数热敏电阻器阻值和温度对应关系的基础上,介绍一种力求非线性最小、能互换、输出电压量和温度量直接对应的温度传感器的简便设计方法。一、热敏电阻器R-T曲线表达式目前普遍的用数学式R_T=R_T1e~(B(1/T-1/T_1))来描述负温度系数热敏电阻器阻值和温度的对应关系。多次实测表明,由上述 Based on the corresponding relationship between the resistance and the temperature of the negative temperature coefficient thermistor, a simple and convenient method for designing a temperature sensor with minimum nonlinearity, interchangeability, direct correspondence between output voltage and temperature is introduced. First, the thermistor R-T curve expression At present, the general formula R_T = R_T1e ~ (B (1 / T-1 / T_1)) to describe the negative temperature coefficient thermistor resistance and temperature correspondence. Multiple actual measurements show that the above
