②測量范圍廣。常用的熱電偶從-50~+1600℃均可邊續(xù)測量，某些特殊熱電偶比較低可測到-269℃（如金鐵鎳鉻），比較高可達(dá)+2800℃（如鎢-錸）。 ③構(gòu)造簡單，使用方便。熱電偶通常是由兩種不同的金屬絲組成，而且不受大小和開頭的限制，外有保護(hù)套管，用起來非常方便。 1．熱電偶測溫基本原理將兩種不同材料的導(dǎo)體或半導(dǎo)體A和B焊接起來，構(gòu)成一個閉合回路。當(dāng)導(dǎo)體A和B的兩個執(zhí)著點1和2之間存在溫差時，兩者之間便產(chǎn)生電動勢,因而在回路中形成一個大小的電流,這種現(xiàn)象稱為熱電效應(yīng)。熱{TodayHot}電偶就是利用這一效應(yīng)來工作的。北京碳化硅熱電偶保護(hù)管廠價直銷奧翔硅碳從國內(nèi)外引進(jìn)了一大批先進(jìn)的設(shè)備，實現(xiàn)了工程設(shè)備的現(xiàn)代化。</p><div

style="text-indent:25px">熱電偶冷端的溫度補償由于熱電偶的材料一般都比較貴重（特別是采用貴金屬時），而測溫點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，熱電偶補償導(dǎo)線的作用只起延伸熱電極，使熱電偶的冷端移動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，不起補償作用。因此，還需采用其他修正方法來補償冷端溫度t0≠0℃時對測溫的影響。在使用熱電偶補償導(dǎo)線時必須注意型號相配，極性不能接錯，補償導(dǎo)線與熱電偶連接端的溫度不能超過100℃。</p><p> 各種熱電偶的外形常因需要而極不相同，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。熱電偶保護(hù)管的應(yīng)用及分類絕緣套管它的作用是防止倆個熱電級之間或熱電級與保護(hù)套管之間短路。絕緣套管的材料由使用溫度范圍確定：在1000°一下多采用普通陶瓷；在1000-1300°之間多采用高純氧化鋁；在1300-1600°之間多采用剛玉，補償導(dǎo)線的絕緣材料多采用有機材料。絕緣保護(hù)管它的作用死熱電偶不直接與被測介質(zhì)相接觸，以防機械損傷或被介質(zhì)腐濁、玷污。由此可見，保護(hù)管是熱電偶在惡劣、特殊環(huán)境下使用的關(guān)鍵。保護(hù)管的材質(zhì)一般根據(jù)測量范圍、加熱區(qū)長度、環(huán)境氣氛以及測溫的時間常數(shù)等條件來決定，主要有金屬、非金屬和金屬陶瓷3種。1.金屬材料，如鋼管、無縫光管、不銹光管和耐熱光管等。金屬保護(hù)管的特點是機械強度高、韌性好、抗熔渣腐濁性強，因此金屬保護(hù)管多數(shù)用于要求有足夠機械強度的場合。但它們在800°以上時，氣密信有所下降。2.非金屬材料。非金屬保護(hù)管主要包括高熔點氧化物及復(fù)合氧化物，如al2o2\sio2、Mgo\ZrO2\Beo等；氮化物，如Si3N4、BN等；碳化物，如SIC等以及硼化物zrb2等。奧翔硅碳始終以適應(yīng)和促進(jìn)工業(yè)發(fā)展為宗旨。</p><div

只與熱電偶的溫度差有關(guān)；若熱電偶冷端的溫度保持一定，這進(jìn)熱電偶的熱電勢*是工作端溫度的單值函數(shù)。將兩種不同材料的導(dǎo)體或半導(dǎo)體A和B焊接起來，構(gòu)成一個閉合回路，如圖所示。當(dāng)導(dǎo)體A和B的兩個執(zhí)著點1和2之間存在溫差時，兩者之間便產(chǎn)生電動勢，因而在回路中形成一個大小的電流。熱電偶就是利用這一效應(yīng)來工作的。在生產(chǎn)中由于被測對象不同，環(huán)境條件不同，測量要求不同，和熱電阻的安裝方法及采取的措施也不同，需要考慮的問題比較多，但原則上可以從測溫的準(zhǔn)確性、安全性、維修方便三個方面來考慮。為避免測溫元件損壞，應(yīng)保證其有足夠的機械強度，為保護(hù)感溫元件不受磨損應(yīng)加保護(hù)屏或保護(hù)管等，為確保安全、可靠，測溫元件的安裝方法應(yīng)視具體情況（如待測介質(zhì)的溫度、壓力、測溫元件的長度及其安裝位置、形式等）而定。下面*舉幾例以引起注意：凡安裝承受壓力的測溫元件，都必須保證其密封性。高溫下工作的熱電偶，為防止保護(hù)管在高溫下產(chǎn)生變形，一般應(yīng)垂直安裝，若必須水平安裝則不宜過長，并用支架保護(hù)熱電偶。若測溫元件安裝于介質(zhì)流速較大的管道中，則其應(yīng)傾斜安裝。為防止測溫元件受到過大的沖蝕，比較好安裝在管道的彎曲處。當(dāng)介質(zhì)壓力超過10MPa時。奧翔硅碳用先進(jìn)的生產(chǎn)工藝和規(guī)范的質(zhì)量管理，打造優(yōu)良的產(chǎn)品！北京碳化硅熱電偶保護(hù)管廠價直銷</p><p
