热电阻分度表怎么看

Pt100，就是说它的阻值在0度时为100欧姆，负200度时为18.52欧姆，200度时为175.86欧姆，800度时为375.70欧姆。

热电阻公式都是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吐露体现摄氏温度，Ro是零摄氏度时的电阻值，A、B、C都是规定的系数，对于Pt100,Ro就等于100。

0到850度

Rt=R0（1+A*t+B*t^2）

-200到0度

Rt=R0[1+A*t+Bt^2+C(t-100)^3] R0是0度是铂电阻的阻值 A=3.940*乘10负3次幂。

B=-5.802乘10负7次幂。

C=-4.274乘10的负12。
