id="e07hjqc" class="box"><p><p style="text-indent:25px">選擇熱電偶要根據使用溫度范圍、所需精度、使用氣氛、測定對象的性能、響應時間和經濟效益等綜合考慮。 1、測量精度和溫度測量范圍的選擇使用溫度在1300~1800℃，要求精度又比較高時，一般選用B型熱電偶；要求精度不高，氣氛又允許可用鎢錸熱電偶，高于1800℃一般選用鎢錸熱電偶；使用溫度在1000~1300℃要求精度又比較高可用S型熱電偶和N型熱電偶；在1000℃以下一般用K型熱電偶和N型熱電偶，低于400℃一般用E型熱電偶；250℃下以及負溫測量一般用T型電偶，在低溫時T型熱電偶穩(wěn)定而且精度高。 2、使用氣氛的選擇 S型、B型、K型熱電偶適合于強的氧化和弱的還原氣氛中使用，J型和T型熱電偶適合于弱氧化和還原氣氛，若使用氣密性比較好的保護管，對氣氛的要求就不太嚴格。 3、耐久性及熱響應性的選擇線徑大的熱電偶耐久性好，但響應較慢一些，對于熱容量大的熱電偶，響應就慢，測量梯度大的溫度時，在溫度控制的情況下，控溫就差。要求響應時間快又要求有一定的耐久性，選擇鎧裝偶比較合適，浙江用于測溫熱電偶保護管廠家，浙江用于測溫熱電偶保護管廠家。 4、測量對象的性質和狀態(tài)對熱電偶的選擇運動物體，浙江用于測溫熱電偶保護管廠家、振動物體、高壓容器的測溫要求機械強度高，有化學污染的氣氛要求有保護管，有電氣干擾的情況下要求絕緣比較高。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

熱電偶因其性能穩(wěn)定、準確可靠、結構簡單、使用方便、測溫范圍廣、信號可遠傳等優(yōu)點，在工業(yè)生產和科學研究等領域中已成為應用**普遍的感溫元件。在其測溫過程中，熱電偶保護管發(fā)揮著重要作用。熱電偶保護管材料性能影響熱電偶的長期穩(wěn)定性和使用壽命等各項性能指標。特別是在高溫下工作的熱電偶，對其材料有更高的要求。比如鋼水連續(xù)測溫，熱電偶保護套管不但要承受高溫，還要受到熾熱鋼水的腐蝕和沖擊。而在循環(huán)流化床鍋爐中測溫時，不但有高溫氧化和高溫腐蝕，還有流動性粉體的高溫沖蝕磨損。如此惡劣的工作環(huán)境對保護套管材料是嚴峻的考驗，也給工程技術人員出了一道難題——如何經濟實用的解決高溫環(huán)境下的熱電偶保護套管的失效問題。**近很多客戶聯(lián)系我們，把他們在熱電偶保護管的使用過程中遇到的問題向我們請教，希望我們能給予幫助，小編就這些問題中的關于熱電偶保護管安裝方面的知識與大家共同探討一下，希望能給廣大客戶朋友們帶來啟發(fā)與幫助，讓大家對熱電偶保護管有一個深層次的了解。這樣大家在以后使用過程中時也能做到心中有數，不慌不忙，發(fā)揮出熱電偶保護管的比較大作用。1、安裝的位置。熱電偶保護管的安裝應盡可能靠近欲測的溫度控制點。</p><div

style="text-indent:25px">熱電偶的種類及結構形成（1）熱電偶的種類常用熱電偶可分為標準熱電偶和非標準熱電偶兩大類。所調用標準熱電偶是指標準規(guī)定了其熱電勢與溫度的關系、允許誤差、并有統(tǒng)一的標準分度表的熱電偶，它有與其配套的顯示儀表可供選用。非標準化熱電偶在使用范圍或數量級上均不及標準化熱電偶，一般也沒有統(tǒng)一的分度表，主要用于某些特殊場合的測量。標準化熱電偶我國從1988年1月1日起，熱電偶和熱電阻全部按IEC國際標準生產，并指定S、B、E、K、R、J、T七種標準化熱電偶為我國統(tǒng)一設計型熱電偶。 (2)熱電偶的結構形式為了保證熱電偶可靠、穩(wěn)定地工作，對它的結構要求如下： ① 組成熱電偶的兩個熱電極的焊接必須牢固； ② 兩個熱電極彼此之間應很好地絕緣，以防短路； ③ 補償導線與熱電偶自由端的連接要方便可靠； ④ 保護套管應能保證熱電極與有害介質充分隔離。</p><div style="width:100%;text-align: center;"><img
