PT100鉑電阻分度表圖
Pt100，就是說它的阻值在0度時為100歐姆，負200度時為18.52歐姆，200度時為175.86歐姆，800度時為375.70歐姆。
熱電阻公式都是Rt=Ro(1+A*t+B*t*t)；Rt=Ro[1+A*t+B*t*t+C(t-100)*t*t*t] 的形式，t吐露體現攝氏溫度，Ro是零攝氏度時的電阻值，A、B、C都是規定的系數，對于Pt100,Ro就等于100。
Rt=R0（1+A*t+B*t^2）
Rt=R0[1+A*t+Bt^2+C(t-100)^3] R0是0度是鉑電阻的阻值 A=3.940*乘10負3次冪。
B=-5.802乘10負7次冪。
C=-4.274乘10的負12。
