R25=50k B25/50=3580 MF52NTC热敏电阻曲线表
来源：本站 更新时间：2015-04-19 22:16:36 查看次数：
NTC热敏电阻因为阻值参数不同所以每个规格都有自己独特和可测量的电阻-温度（R/T）特性，这些特性也被称之为R/T曲线，这种R/T特性是非线性的，斯坦哈特-Hart公式非常准确地描述R / T曲线[1,2,3]：1 / T = A + B（LNR）+ C（LNR）3 其中：T =绝对温度R =电阻在温度T系数A，B和C通过校正在三个温度点，然后求解三个联立方程得出。 与使用斯坦哈特 - Hart方程式相关的不确定度小于±0.005℃，在0°C-260°C的温度范围在50°C的温度跨度，因此采用适当的内插公式或查找表中与微处理器相结合可以消除潜在的非线性问题。
