摘要
介绍一种热敏电阻温度传感器非线性校正的原理和校正电路。校正后传感器的输出电压与绝对温度的比值约为1mV/K,最大误差不超过1.5%,基本呈线性关系。
This paper introduces the principle of non-linear calibration for a thermistor temperature sensor and the calibration circuit. After calibration,the ratio of the output voltage of the sensor vs the absolute temperature is round ,the maximum error is winthin 1.5%. The characteristic is linear basically.
