Abstract

Negative temperature coefficient thermistors have a high degree of nonlinearity in the resistance–temperature curve, which needs to be fitted with equations in practical applications. The effects of the number of selected points and the way of point selection on the fitting results of different equations in the range of (−50 to 100) °C are explored, and the results show that selecting 11 fitting points with the temperature/resistance combination method can improve the accuracy of S–H fitting, which is suitable for fields with lower precision requirements. For high-precision measurements, the Hoge-2 and Hoge-3 equations should be used with a temperature uniformity point selection method, and the optimal number of fitting points is 11 and 6, respectively.

负温度系数热敏电阻选点策略研究
负温度系数热敏电阻的电阻-温度曲线具有高度的非线性,在实际应用中需要用方程进行拟合。探讨了在 (-50 至 100) ℃ 范围内,选择点的数量和选择点的方式对不同方程拟合结果的影响,结果表明,用温度/电阻组合法选择 11 个拟合点可以提高 S-H 拟合的精度,适用于精度要求较低的领域。对于高精度测量,Hoge-2 和 Hoge-3 方程应与温度均匀性点选择方法一起使用,最佳拟合点数分别为 11 和 6。
