pt1000是铂热电阻，它的阻值会随着温度的变化而改变。
PT后的1000即表示它在0℃时阻值为1000欧姆，在300℃时它的阻值约为2120.515欧姆。它的工业原理：当PT1000在0摄氏度的时候他的阻值为1000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。
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。

常见的pt1000感温元件有陶瓷元件，玻璃元件，云母元件，它们是由铂丝分别绕在陶瓷骨架，玻璃骨架，云母骨架上再经过复杂的工艺加工而成。
薄膜铂电阻：用真空沉积的薄膜技术把铂溅射在陶瓷基片上，膜厚在2微米以内，用玻璃烧结料把Ni（或Pd）引线固定，经激光调阻制成薄膜元件。
