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℃。
