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,通常與溫度變送器思袋、調(diào)節(jié)器及顯示儀表等配套使用,組成過程控制系統(tǒng)聪供,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、蒸汽和氣體介質以及固體表面等溫度估骡。
:
應用
通常和顯示儀表、記錄儀表筝妥、電子計算機等 配套使用暮霍,直接測量各種生產(chǎn)過程中0~1800℃范圍內(nèi)的液體、蒸汽和氣體介質以及固體表面 溫度屋问。
特點裝配簡單串篓、更換方便 壓簧式感溫元件,抗振性能好 測量范圍大 機械強度高籍囱,耐壓性能好
工作原理
熱電偶的工作原理是:兩種不同成分的導體兩端經(jīng)焊接绩寂、形成回路茶括,直接測溫端叫測量端,接線端子端叫參比端佃戈。當測量端和參比端存在溫差時诅福,就會在回路中產(chǎn)生熱電勢,接上顯示儀表拖叙,儀表上就指示出熱電偶所產(chǎn)生的熱電動勢的對應溫度值氓润。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體材質以及兩端溫差有關薯鳍,與熱電極的長度咖气、直徑無關。
裝配式熱電偶主要由接線盒挖滤、保護管崩溪、絕緣套管、接線端子斩松、熱電極組成基本結構悯舟,并配以各種安裝固定裝置組成。
熱電偶的工作原理是:兩種不同成分的導體兩端經(jīng)焊接砸民、形成回路抵怎,直接測溫端叫測量端,接線端叫參比端岭参。當測量和參比端存在溫差時反惕,就會在回路時產(chǎn)生熱電流,接上顯示儀表麸奇,儀表上就指示出熱電偶所產(chǎn)生的熱電動勢的對應溫度值马怎。
熱電偶的熱電動熱勢將隨著測量端溫度升高面增長,熱電動熱勢的大小只和熱電偶導體材質以及兩端溫差有關票援、和熱電極的長度惰渐、直徑無關。
裝配式熱電偶主要由接線盒膊争、保護管校社、絕緣套管、接線端子渣碌、熱電太組成基本結構欠怕,閾配以各安裝固定裝置組成。
