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(biāo)準(zhǔn)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(biāo)準(zhǔn)生產(chǎn)，并指定S、B、E、K、R、J、T七種標(biāo)準(zhǔn)化熱電偶為我國統(tǒng)一設(shè)計型熱電偶。 (2)熱電偶的結(jié)構(gòu)形式為了保證熱電偶可靠、穩(wěn)定地工作，對它的結(jié)構(gòu)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(yīng)很好地絕緣，以防短路； ③ 補償導(dǎo)線與熱電偶自由端的連接要方便可靠； ④

但耐高溫性卻不夠良金屬材料保護套管性能表好，易受腐蝕。常用的金屬材料保護套管如表1所示。[1]2非金屬材料該類材料的特點是：耐高溫、抗氧化，但不抗沖擊，比較脆易碎，導(dǎo)熱性不理想，熱響應(yīng)敏感性差。因此，一般要求管壁比較薄，因而帶來一系列問題。隨著科技的進步，溫度測量技術(shù)得到迅速發(fā)展，已形成從點到線、由線到面；由表及里；從有線到無線的發(fā)展趨勢。在接觸式與非接觸式兩大類產(chǎn)品中，量大面廣的接觸式熱電偶在現(xiàn)代技術(shù)發(fā)展中得到了快速的發(fā)展。熱電偶因其性能穩(wěn)定、準(zhǔn)確可靠、結(jié)構(gòu)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(chǎn)和科學(xué)研究等領(lǐng)域中已成為應(yīng)用**普遍的感溫元件。在其測溫過程中，熱電偶保護套管發(fā)揮著重要作用。套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(biāo)。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。
