一體化溫度變送器通常由測溫探頭（熱電偶或熱電阻傳感器）和兩線制固體電子單元構(gòu)成。選用固體模塊方式將測溫探頭直接安裝在接線盒內(nèi)，然后構(gòu)成一體化的變送器。一體化溫度變送器通常分為熱電阻和熱電偶型兩種類型。熱電阻溫度變送器是由基準(zhǔn)單元、R/V變換單元、線性電路、反接維護(hù)、限流維護(hù)、V/I變換單元等構(gòu)成。測溫?zé)犭娮栊盘栕儞Q擴(kuò)大后，再由線性電路對溫度與電阻的非線性關(guān)系進(jìn)行抵償，經(jīng)V/I變換電路后輸出一個(gè)與被測溫度成線性關(guān)系的4～20mA的恒流信號。熱電偶溫度變送器通常由基準(zhǔn)源、冷端抵償、擴(kuò)大單元、線性化處理、V/I變換、斷偶處理、反接維護(hù)、限流維護(hù)等電路單元構(gòu)成。它是將熱電偶發(fā)生的熱電勢經(jīng)冷端抵償擴(kuò)大后，再帽由線性電路消除熱電勢與溫度的非線性差錯(cuò)，終擴(kuò)大變換為4～20mA電流輸出信號。為避免熱電偶測量中由于電偶斷絲而使控溫失效形成事故，變送器中還設(shè)有斷電維護(hù)電路。當(dāng)熱電偶斷絲或接解不良時(shí)，變送器會(huì)輸出大值（28mA）以使外表堵截電源。 </p><p> 熱電偶冷端的溫度補(bǔ)償: </p> <p> 由于熱電偶的材料一般都比較貴重(特別是采用貴金屬時(shí))，而測溫點(diǎn)到儀表的距離都很遠(yuǎn)，為了節(jié)省熱電偶材料，降低成本，通常采用補(bǔ)償導(dǎo)線把熱電偶的冷端(自由端)延伸到溫度比較穩(wěn)定的控制室內(nèi)，連接到儀表端子上。必須指出，熱電偶補(bǔ)償導(dǎo)線的作用只起延伸熱電極，使熱電偶的冷端移動(dòng)到控制室的儀表端子上，它本身并不能消除冷端溫度變化對測溫的影響，不起補(bǔ)償作用。因此，還需采用其他修正方法來補(bǔ)償冷端溫度t0≠0℃時(shí)對測溫的影響。 </p> <p> 在使用熱電偶補(bǔ)償導(dǎo)線時(shí)必須注意型號相配，極性不能接錯(cuò)，補(bǔ)償導(dǎo)線與熱電偶連接端的溫度不能超過100℃。 DIN導(dǎo)軌裝置、儀表盤裝置型溫度變送器裝置和保護(hù)簡略，能夠經(jīng)過改動(dòng)組態(tài)來匹配不一樣類型的溫度傳感器。</p><div

溫度變送器在投入現(xiàn)場使用過程中，套管破裂的原因有多種因素，針對這種情況的，我們要具體問題具體分析，理論實(shí)際相結(jié)合。導(dǎo)致溫度變送器套管破裂的原因：1、溫度變送器受高速流體沖擊，載負(fù)過大，應(yīng)力[1]超過極限，導(dǎo)致套管破裂；2、溫度變送器所在的管道振動(dòng)過大，造成套管疲勞損壞；3、流體流經(jīng)溫度變送器套管時(shí)，誘發(fā)溫度變送器套管振動(dòng)，即溫度變送器套管固有頻率和流體旋渦脫落頻率產(chǎn)生共振。這種共振現(xiàn)象會(huì)導(dǎo)致溫度變送器套管損壞速度加快，以致斷裂。4、溫度變送器套管本身的加工缺陷，容易造成套管斷裂。一體化溫度變送器用途</p></p><br
