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。
