錐形套管比直形套管具有更高的自然頻率，因此抗流體沖擊能力和抗振能力更強。并且因錐形套管的前端直徑比直形套管的前端直徑更細，因此保證了更快的反應(yīng)速度。根據(jù)上述兩點闡述，對于套管形式，推薦選用錐形套管，且大小端直徑差不小于6mm。三、熱電偶保護管直徑的選擇：根據(jù)壓力等級的不同，套管直徑也應(yīng)合理選用，江蘇碳化硅熱電偶保護管廠家，如用于中低壓場合的套管直徑可選用大小端直徑Φ25/19mm，用于高壓場合的套管直徑可選用大小端直徑Φ32/21mm等。四、熱電偶保護管安裝方式的選擇：熱電偶熱電阻套管的安裝方式有法蘭、螺紋、焊接3種。焊接式一般是根據(jù)現(xiàn)場需要而定，江蘇碳化硅熱電偶保護管廠家，對于法蘭和螺紋兩種方式，江蘇碳化硅熱電偶保護管廠家，推薦使用法蘭安裝，原因有以下幾點：·對于壓力等級較高的場合，螺紋安裝不適宜，只能用法蘭安裝?！τ诟g性場合，螺紋安裝易因腐蝕而無法拆卸，此時必須選擇法蘭安裝?！ぴ谠O(shè)備上使用，一般選用法蘭安裝?！τ跍囟雀哂?30℃的場合，螺紋易發(fā)生高溫間隙變形，所以應(yīng)選用法蘭安裝。綜合上述幾點，在螺紋和法蘭之間，推薦選用法蘭安裝。

長期工作溫度0-800度，比較高工作溫度0-1000度。　　2、鎳鉻-鎳硅熱電偶 K 長期工作溫度0-1000度，比較高工作溫度0-1300度。　　3、鉑銠10-鉑熱電偶 S 長期工作溫度0-1300度，比較高工作溫度0-1600度　　4、鉑銠30-鉑銠6熱電偶B 長期工作溫度0=1600度，比較高工作溫度0-1800度　　所以熱電偶使用壽命一般只考慮了高溫氧化氣氛下熱電偶電極、保護管的耐受能力，還沒有將高溫環(huán)境下各種還原性氣體、腐蝕性氣體、液體對保護管、電極的侵蝕計算在內(nèi)，而高溫腐蝕又是熱電偶的比較大克星</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇碳化硅熱電偶保護管廠家" src="https://tyunfile.71360.com/UploadFile/zbwuzi/637238610543115234/5363422.jpg"></div><p> 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，為保護感溫元件不受磨損應(yīng)加保護屏或保護管等，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。</p><div
