二線制：在熱電阻的兩端各連接根導線來引出電阻信號的方式叫二線制：這種引線方法很簡單，但由于連接導線必然存在引線電阻r，r大小與導線的材質(zhì)和長度的因素有關(guān)，因此這種引線方式只適用于測量精度較低的場合 　　○2三線制：在熱電阻的根部的端連接根引線，另端連接兩根引線的方式稱為三線制，這種方式通常與電橋配套使用，可以較好的消除引線電阻的影響，是工業(yè)過程控制中的zui常用的[1]。 　　○3四線制：在熱電阻的根部兩端各連接兩根導線的方式稱為四線制，其中兩根引線為熱電阻提供恒定電流I，把R轉(zhuǎn)換成電壓信號U，再通過另兩根引線把U引二次儀表?？梢娺@種引線方式可*消除引線的電阻影響，主要用于高精度的溫度檢測。 　　熱電阻采用三線制接法。采用三線制是為了消除連接導線電阻引起的測量誤差。這是因為測量熱電阻的電路般是不平衡電橋。熱電阻作為電橋的個橋臂電阻，其連接導線（從熱電阻到中控室）也成為橋臂電阻的部分，這部分電阻是未知的 　　且隨環(huán)境溫度變化，造成測量誤差。采用三線制，將導線根接到電橋的電源端，其余兩根分別接到熱電阻所在的橋臂及與其相鄰的橋臂上，這樣消除了導線線路電阻帶來的測量誤差
