概述
其優(yōu)點很多,零件分解性好,維修方便,更換易損件成本低可以遠傳電信號,靈敏度高,穩(wěn)定性強,互換性以及準確性都比較好。裝配鉑熱電阻的常溫絕緣電阻應不小于100MΩ,裝配銅熱電阻的常溫絕緣電阻應不小于50MΩ等特點。廣泛應用于石油、化工等生產(chǎn)現(xiàn)場伴有各種易燃、易爆氣體、蒸汽的場合。
WZ系列工業(yè)用熱電阻作為溫度測量傳感器,通常與溫度變送器,調(diào)節(jié)器以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-200℃-500℃范圍內(nèi)的液體,蒸汽和氣體介質(zhì)以及固體表面的溫度.。
熱電阻是利用物質(zhì)在溫度變化時本身電阻也隨著發(fā)生變化的特性來測量溫度的。當被測介體中有溫度剃度存在時,所測的溫度是感溫元件所在范圍介質(zhì)中的平均溫度。
盡管各種熱電阻的外形差異很大,但是它們的基本結(jié)構(gòu)卻大致相似,一般有感溫元件,絕緣套管,保護管,和接線盒等主要部分組成。
工作原理
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。當阻值變化時,工作儀表便顯示出阻值所對應的溫度值。
裝配式熱電阻由感溫元件、外保護管、接線盒以及各種用途的固定裝置組成,有單支和雙支元件兩種規(guī)格,保護管不但具有抗腐蝕性能,而且具有足夠的機械強度,保證產(chǎn)品能安全地使用在各種場合。測溫原理:受熱后的金屬絲電阻隨著溫度的變化而變,其熱電阻值R(t)與其所處溫度t的關系可表示為:R(t)=R0(1+At+Bt2+……),按測得的電阻值查相應分度表即可得出被測溫度值t。
特點
抗振性能好;
測溫精度高;
機械強度高;
耐壓性能好;
性能可靠穩(wěn)定;
零件分解性好;
維修方便;
更換易損件成本低;
熱響應時間短。熱響應時間:在溫度出現(xiàn)階躍變化,熱電阻的輸出變化至相當于該階躍變化的50%所需的時間,成為熱響應時間,用T0.5表示。
公稱壓力:一般是指在常溫下,保護管所能承受靜態(tài)外壓不破裂,試驗壓力一般采用公稱壓力的1.5倍。實際上,允許公稱壓力不僅與保護管材料、直徑、壁厚有關,而且還與其結(jié)構(gòu)形式、安裝方法、置入深度以及被測介質(zhì)的流速、種類有關
