非金屬保護(hù)管主要用于高溫，也可在不宜用金屬套管的低溫中使用。其抗腐濁性強(qiáng)，但是質(zhì)地較脆。3.金屬陶瓷。金屬材料雖然堅(jiān)韌，但往往不耐高溫以及抗腐濁性差。陶瓷材料恰好相反，它們能耐高溫、抗腐濁，但是很脆。為此，重慶耐腐蝕熱電偶保護(hù)管公司，人們將金屬與陶瓷結(jié)合，集倆者之優(yōu)點(diǎn)，得到了一種即耐高溫、抗腐濁，又抗熱震的堅(jiān)韌材料--金屬陶瓷。所謂金屬陶瓷，是指一種金屬或合金，同一種或幾種陶瓷材料組成的非均值的復(fù)合材料。主要有AL2O3基金屬陶瓷、ZRO2基金屬陶瓷、mgo基金屬陶瓷和碳化鈦系列金屬陶瓷。金屬陶瓷保護(hù)管常用于化工廠、溶融金屬和高溫爐的溫度測(cè)量.熱電偶保護(hù)管是保護(hù)熱電偶芯的套管。1、熱電偶（thermocouple）是溫度測(cè)量?jī)x表中常用的測(cè)溫元件，它直接測(cè)量溫度，并把溫度信號(hào)轉(zhuǎn)換成熱電動(dòng)勢(shì)信號(hào)，重慶耐腐蝕熱電偶保護(hù)管公司，通過電氣儀表（二次儀表）轉(zhuǎn)換成被測(cè)介質(zhì)的溫度。2、各種熱電偶的外形常因需要而極不相同，重慶耐腐蝕熱電偶保護(hù)管公司，但是它們的基本結(jié)構(gòu)卻大致相同，通常由熱電極、絕緣套保護(hù)管和接線盒等主要部分組成，通常和顯示儀表、記錄儀表及電子調(diào)節(jié)器配套使用。熱電偶（thermocouple）是溫度測(cè)量?jī)x表中常用的測(cè)溫元件，它直接測(cè)量溫度，并把溫度信號(hào)轉(zhuǎn)換成熱電動(dòng)勢(shì)信號(hào)，通過電氣儀表。</p><div

多點(diǎn)式熱電偶。多支不同長(zhǎng)度的熱電偶感溫元件，用多孔的絕緣管組裝而成。適合于化工生產(chǎn)中反應(yīng)器不同高度的幾何溫度測(cè)量，如合成塔不同位置的溫度。隔爆型熱電偶。隔爆型熱電偶基本參數(shù)與普通型熱電偶一樣，區(qū)別在于采用了防爆結(jié)構(gòu)的接線盒。當(dāng)生產(chǎn)現(xiàn)場(chǎng)存在易燃易爆氣體的條件下必須使用隔爆型熱電偶。表面型熱電偶。表面型熱電偶是利用真空鍍膜法將兩電極材料蒸鍍?cè)诮^緣基底上的薄膜熱電偶，專門用于測(cè)量各種形狀的固體表面溫度，如測(cè)量軸承、軋錕等表面溫度、測(cè)量設(shè)備或高壓容器的表面溫度等。反應(yīng)速度極快，熱慣性極小，可作為一種便攜式測(cè)溫計(jì)。此外還有一些特殊場(chǎng)合用熱電偶，如耐磨熱電偶、適用于流化床中測(cè)量床層溫度，能經(jīng)受催化劑的沖刷、摩擦。在超高溫（大于2000℃）場(chǎng)合可選用碳-碳化硅熱電偶（比較高測(cè)溫可達(dá)2700℃）和鎢鋅熱電偶（比較高測(cè)溫可達(dá)2800℃）。在**溫（低于-200℃以下）場(chǎng)合可選金鈦-鎳鉻熱電偶-金鐵熱電偶，這種電偶低溫穩(wěn)定性好，靈敏度高，比較低測(cè)溫可達(dá)-271℃，主要用于宇航及超導(dǎo)等**溫過程。熱電偶直接測(cè)量溫度，并把溫度信號(hào)轉(zhuǎn)換成熱電動(dòng)勢(shì)信號(hào)，通過電氣儀表（二次儀表）轉(zhuǎn)換成被測(cè)介質(zhì)的溫度。</p><div
