電站熱電阻專業(yè)針對電站設(shè)計,可以滿足30萬,60萬千瓦等發(fā)電機組及輔機測溫需要。直接測量各種生產(chǎn)過程中 的-200°C~800°C范圍內(nèi)液體、蒸汽和氣體介質(zhì)以及固體表面溫度。
電站熱電阻的工作原理熱電偶的電極由兩根不同導(dǎo)體材質(zhì)組成。當(dāng)測量端與參比端存在溫差時,就會產(chǎn)生熱電勢,工作儀表 便顯示出熱電勢所對應(yīng)的溫度值。熱電阻是利用物質(zhì)在溫度變化時,其電阻也隨著發(fā)生變化的特征來測量溫度的。當(dāng)阻值變化時,工作儀表便顯示出阻值所對應(yīng)的溫度值。電站熱電阻的技術(shù)參數(shù)產(chǎn)品執(zhí)行標準:IEC584IEC751IEC1515JB/T18622-1997JB/T8623-1997GB/T16839-1997電站熱電阻測量范圍及允差
