设计原理pt100是铂热电阻，简称为：PT100铂电阻，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。

PT100铂热敏电阻是一种铂电阻，其电阻值会随温度的变化而变化。
Pt之后的100表示其电阻在0℃为100 ohm，在100℃为138.5 ohm。
在编辑医疗，电气，工业，温度计算，卫星，天气，电阻计算等高精度温度设备中，应用范围非常广泛。
PT100铂热敏电阻在工业上是常用的。
从电阻随温度的变化来看，大多数金属导体都具有这种特性，但并不是所有的金属导体都可以用作热阻。
金属材料对热阻的一般要求如下：尽可能大且稳定的温度系数，大电阻率（在相同灵敏度下减小传感器的尺寸）和使用温度范围具有稳定的化学和物理性能，良好材料的可复制性，以及电阻和温度之间的函数关系。
PT100铂电阻温度对照表第一类：50°119.40Ω; 100°138.51Ω; 150°157.33Ω;200°175.86Ω。
这是比例为0.003851的PT100。
它也是最常见的PT100指数。
第二种：50°119.70Ω; 100°139.10Ω; 150°158.21Ω;200°177.03Ω; 250°195.56Ω; 300°213.79Ω; 350°231.73Ω;这是比例为0.003910的PT100，称为Ba2刻度。
通常，未指定的PT100是指比例为0.003851的PT100。
两线制系统测得的电阻为引线电阻。
用三根线和四根线测量的电阻是电阻的电阻值，并且已经减去了引线的电阻值。
通常，高精度PT100不会使用两线制系统。
对于所有PT100电阻器，正常情况下，您测量的电阻值是不同的。
只要测量的电阻值的偏差在精度水平的公差范围内，就可以满足要求。
如果是PT100，则其0度电阻范围在99.941〜100.059欧姆范围内是合格的。

Pt100铂电阻温度与电阻对照
一、Pt100温度传感器的主要技术参数：
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。
二、热电阻公式:
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，对于Pt100,Ro就等于100
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
三、比较简洁的计算方法：
PT100在0摄氏度的时候电阻值为100欧姆，然后温度每升高一度，电阻值增加0.385欧姆，具有良好的线性。
