設計原理
PT後的1000即表示它在0℃時阻值為1000歐姆，在300℃時它的阻值約為2120.515歐姆。它的工業原理：當PT1000在0攝氏度的時候他的阻值為1000歐姆，它的的阻值會隨著溫度上升它的阻值是成勻速增漲的。
套用範圍
醫療、電機、工業、溫度計算、阻值計算等高精溫度設備，套用範圍非常之廣泛。

組成部分
常見的pt1000感溫元件有陶瓷元件，玻璃元件，雲母元件，它們是由鉑絲分別繞在陶瓷骨架，玻璃骨架，雲母骨架上再經過複雜的工藝加工而成。
薄膜鉑電阻
薄膜鉑電阻：用真空沉積的薄膜技術把鉑濺射在陶瓷基片上，膜厚在2微米以內，用玻璃燒結料把Ni（或Pd）引線固定，經雷射調阻製成薄膜元件。
