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。
