<p> 熱電阻是把溫度變化轉換為電阻值變化的一次元件，通常需要把電阻信號通過引線傳遞到計算機控制裝置或者其它一次儀表上。工業(yè)用熱電阻安裝在生產現場，與控制室之間存在一定的距離，因此熱電阻的引線對測量結果會有較大的影響。 </p> <p> 目前熱電阻的引線主要有三種方式： </p> <p> 二線制：在熱電阻的兩端各連接一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大小與導線的材質和長度的因素有關，因此這種引線方式只適用于測量精度較低的場合 </p> <p> 三線制：在熱電阻的根部的一端連接一根引線，資陽熱電阻哪家好，另一端連接兩根引線的方式稱為三線制，資陽熱電阻哪家好，這種方式通常與電橋配套使用，資陽熱電阻哪家好，可以較好的消除引線電阻的影響，是工業(yè)過程控制中的常用的。資陽熱電阻哪家好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
