概述
其優(yōu)點(diǎn)很多,零件分解性好,維修方便,更換易損件成本低可以遠(yuǎn)傳電信號(hào),靈敏度高,穩(wěn)定性強(qiáng),互換性以及準(zhǔn)確性都比較好。裝配鉑熱電阻的常溫絕緣電阻應(yīng)不小于100MΩ,裝配銅熱電阻的常溫絕緣電阻應(yīng)不小于50MΩ等特點(diǎn)。廣泛應(yīng)用于石油、化工等生產(chǎn)現(xiàn)場(chǎng)伴有各種易燃、易爆氣體、蒸汽的場(chǎng)合。
WZ系列工業(yè)用熱電阻作為溫度測(cè)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(guò)程控制系統(tǒng),用以直接測(cè)量或控制各種生產(chǎn)過(guò)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(shí)本身電阻也隨著發(fā)生變化的特性來(lái)測(cè)量溫度的。當(dāng)被測(cè)介體中有溫度剃度存在時(shí),所測(cè)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(hù)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(shí),其電阻也隨著發(fā)生變化的特征來(lái)測(cè)量溫度的。當(dāng)阻值變化時(shí),工作儀表便顯示出阻值所對(duì)應(yīng)的溫度值。
裝配式熱電阻由感溫元件、外保護(hù)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(hù)管不但具有抗腐蝕性能,而且具有足夠的機(jī)械強(qiáng)度,保證產(chǎn)品能安全地使用在各種場(chǎng)合。測(cè)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(guān)系可表示為:R(t)=R0(1+At+Bt2+……),按測(cè)得的電阻值查相應(yīng)分度表即可得出被測(cè)溫度值t。

熱響應(yīng)時(shí)間短。熱響應(yīng)時(shí)間:在溫度出現(xiàn)階躍變化,熱電阻的輸出變化至相當(dāng)于該階躍變化的50%所需的時(shí)間,成為熱響應(yīng)時(shí)間,用T0.5表示。
公稱壓力:一般是指在常溫下,保護(hù)管所能承受靜態(tài)外壓不破裂,試驗(yàn)壓力一般采用公稱壓力的1.5倍。實(shí)際上,允許公稱壓力不僅與保護(hù)管材料、直徑、壁厚有關(guān),而且還與其結(jié)構(gòu)形式、安裝方法、置入深度以及被測(cè)介質(zhì)的流速、種類(lèi)有關(guān)
