PT100熱電阻常用計(jì)算公式及分度表

  通常熱電阻（鉑熱電阻）產(chǎn)品是由熱電阻測溫芯片與外保護(hù)套管、連接件、接線盒等組成的，熱電阻作為測量介質(zhì)溫度的溫度傳感器可以與顯示儀表、記錄儀表、控制儀表配套使用，直接測量或控制生產(chǎn)過程中-200℃~600℃范圍內(nèi)的各種介質(zhì)的溫度，熱電阻屬于非標(biāo)訂制產(chǎn)品，可以根據(jù)用戶的不同安裝、使用等要求進(jìn)行訂制生產(chǎn)，選用的熱電阻Pt100芯片為進(jìn)口芯片，輸出信號(hào)為阻值信號(hào)Ω值，我們常用的熱電阻接線有兩線制、三線制與四線制，通常以三線制接線方式為主，一般熱電阻PT100三線制AB=AC=100Ω時(shí)對(duì)應(yīng)溫度顯示為0℃，溫度每升高1℃，電阻阻值大概升高0.385Ω，這樣依次類推即可知道我們實(shí)際溫度與熱電阻測量溫度的大概偏差，所以一般只要我們操作人員在現(xiàn)場只要通過萬用表實(shí)際斷電拆線后直接測量熱電阻接線端子上的電阻值與工藝大概溫度判斷一下就會(huì)知道熱電阻的好壞了，要想了解更加準(zhǔn)確的溫度，就需要通過PT100熱電阻分度表對(duì)照查詢即可：
