pt100电阻与温度对应表.pt100电阻与温度对应表设计原理:pt100是铂热电阻,它的阻值会随着温度的变化而改变。
PT 后的100即表示它在0℃时阻值为100欧姆,在100℃时它的阻值约为138.5欧姆。
它的工业原理:当PT100在0摄氏度的时候他的阻值为100欧姆,它的的阻值会随着温度上升它的阻值是成匀速增涨的。
应用范围:医疗、电机、工业、温度计算、阻值计算等高精温度设备,应用范围非常之广泛。

Pt100热电阻计算公式及分度表
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表示摄氏温度，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
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
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。
Pt100温度传感器的主要技术参数如下：测量范围：-200℃～+850℃；允许偏差值△℃：A 级±（0.15＋0.002│t│），B级±（0.30＋0.005│t│）；热响应时间<30s；最小置入深度：热电阻的最小置入深度≥200mm；允通电流≤5mA。
另外，Pt100温度传感器还具有抗振动、稳定性好、准确度高、耐高压等优点。
看到了？电流不能大于5mA，而电阻是随温度变化的，所以电压也要注意。
为了提高温度测量的准确性，应使用1V电桥电源、A/D转换器的5V参考电源要稳定在1mV级；在价格允许的情况下，Pt100传感器、A/D转换器和运放的线性度要高。
同时，利用软件矫正其误差，可以使测得温度的精度在±0.2℃。
