熱電阻分度表怎么看

Pt100，就是說它的阻值在0度時(shí)為100歐姆，負(fù)200度時(shí)為18.52歐姆，200度時(shí)為175.86歐姆，800度時(shí)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(xiàn)攝氏溫度，Ro是零攝氏度時(shí)的電阻值，A、B、C都是規(guī)定的系數(shù)，對(duì)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度是鉑電阻的阻值 A=3.940*乘10負(fù)3次冪。

B=-5.802乘10負(fù)7次冪。

C=-4.274乘10的負(fù)12。
