熱電偶或熱電阻傳感器將被測溫度轉(zhuǎn)換成電信號，再將該信號送入變送器的輸入網(wǎng)絡(luò)，該網(wǎng)絡(luò)包含調(diào)零和熱電偶補(bǔ)償?shù)认嚓P(guān)電路。經(jīng)調(diào)零后的信號輸入到運(yùn)算放大器進(jìn)行信號放大，放大的信號一路經(jīng)v/i轉(zhuǎn)換器計(jì)算處理后以4－20ma直流電流輸出；另一路經(jīng)a/d轉(zhuǎn)換器處理后到表頭顯示。變送器的線性化電路有兩種，均采用反饋方式。對熱電阻傳感器，用正反饋方式校正，對熱電偶傳感器，用多段折線逼近法進(jìn)行校正。一體化數(shù)字顯示溫度變送器有兩種顯示方式。lcd顯示的溫度變送器用兩線制方式輸出，led顯示的溫度變送器三線制方式輸出。防水型溫度變送器介紹溫度變送器模塊是一種添加了部分智能電阻板的智能化模塊，可與各類儀器儀表配套使用。</p><div

1、當(dāng)心將電纜連接器徹底縮攏到內(nèi)部護(hù)罩內(nèi)。在將電纜連接器徹底縮攏到內(nèi)部護(hù)罩內(nèi)之前，禁止撤除外殼。在旋轉(zhuǎn)外殼時(shí)護(hù)罩可避免電纜遭到損壞。 </p> <p> 2、用 9/64” 六角頭扳手松開外殼旋轉(zhuǎn)定位螺釘并旋出一圈螺紋。為避免損壞傳感器模塊帶狀電纜，在從電氣外殼撤除傳感器模塊前將帶狀電纜從電子線路板撤除。 </p> <p> 3、從模塊處將外殼旋松，保證護(hù)罩和傳感器電纜與外殼沒有纏結(jié)。當(dāng)旋轉(zhuǎn)外殼時(shí)應(yīng)保證傳感器帶狀電纜和內(nèi)部護(hù)罩與外殼徹底脫離。假如內(nèi)部護(hù)罩和傳感器帶狀電纜與外殼纏掛或與外殼一起旋轉(zhuǎn)，將損壞電纜。 </p><p> 我們應(yīng)該怎樣保護(hù)溫度變送器免受浪涌的危害呢？ </p> <p> 浪涌保護(hù)器，也叫防雷器，是一種為各種電子設(shè)備、儀器儀表、通訊線路提供安全防護(hù)的電子裝置。能夠有效的防止浪涌度溫度變送器的危害。當(dāng)電氣回路或者通信線路中因?yàn)橥饨绲母蓴_突然產(chǎn)生尖峰電流或者電壓時(shí)，浪涌保護(hù)器能在極短的時(shí)間內(nèi)導(dǎo)通分流，從而避免浪涌對回路中溫度變送器的損害。除了給溫度變送器添加浪涌保護(hù)器外，在現(xiàn)場也要做好各種接地、絕緣、屏蔽、保護(hù)電路等保護(hù)措施。這樣不僅能保護(hù)溫度變送器，在整個系統(tǒng)中的其他設(shè)備也能免受浪涌帶來的損壞，保證我們的儀器儀表正常運(yùn)行。一體化溫度變送器的輸出為統(tǒng)一的4~20mA信號;可與微機(jī)系統(tǒng)或其它常規(guī)儀表匹配使用。</p><div

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，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)，變送器會輸出大值（28mA）以使外表堵截電源。一體化溫度變送器能夠直接與溫度傳感器的DIN銜接頭相接，具有裝置花費(fèi)較低，體積小。西安普通溫度變送器推薦</p><p
