WR系列工業(yè)用鉑銠熱電偶又叫貴金屬熱電偶,它作為溫度測量傳感器,通常與溫度變送器、調(diào)節(jié)器及顯示儀表等配套使用,組成過程控制系統(tǒng),用以直接測量或控制各種生產(chǎn)過程中0-1800℃范圍內(nèi)的流體、蒸汽和氣體介質(zhì)以及固體表面等溫度。
:
應(yīng)用
通常和顯示儀表、記錄儀表、電子計算機(jī)等 配套使用,直接測量各種生產(chǎn)過程中0~1800℃范圍內(nèi)的液體、蒸汽和氣體介質(zhì)以及固體表面 溫度。
特點裝配簡單、更換方便 壓簧式感溫元件,抗振性能好 測量范圍大 機(jī)械強(qiáng)度高,耐壓性能好
工作原理
熱電偶的工作原理是:兩種不同成分的導(dǎo)體兩端經(jīng)焊接、形成回路,直接測溫端叫測量端,接線端子端叫參比端。當(dāng)測量端和參比端存在溫差時,就會在回路中產(chǎn)生熱電勢,接上顯示儀表,儀表上就指示出熱電偶所產(chǎn)生的熱電動勢的對應(yīng)溫度值。熱電偶的熱電動勢將隨著測量端溫度升高而增長,熱電動勢的大小只與熱電偶導(dǎo)體材質(zhì)以及兩端溫差有關(guān),與熱電極的長度、直徑無關(guān)。
裝配式熱電偶主要由接線盒、保護(hù)管、絕緣套管、接線端子、熱電極組成基本結(jié)構(gòu),并配以各種安裝固定裝置組成。
