對于爐管刀刃熱電偶電動勢需要注意的幾個方面

發布時間:2021-09-24      點擊次數:466
   爐管刀刃熱電偶是為煉油、電力、冶金、機械、食品加熱爐爐管表面高溫場所的溫度測重而設計的。其構造是由防水接線盒與刀刃頭的鎧裝式感溫元件(端均為接殼型式)卡,和可動定位圓組合而成。

  爐管刀刃熱電偶實際上是-種能里轉換器,它將熱能轉換為電能,用所產生的熱電勢測里溫度,對于熱電偶的熱電勢,應注意如下幾個問題:
  1:熱電偶的熱電勢是熱電偶兩端溫度函數的差,而不是熱電偶兩端溫度差的函數。
  2:當熱電偶的兩個熱電偶絲材料成份確定后,熱電偶熱電勢的大小,只與熱電偶的溫度差有關;若熱電偶冷端的溫度保持一定,這進熱電偶的熱電勢僅是工作端溫度的單值函數。
  3:熱電偶所產生的熱電勢的大小,當熱電偶的材料是均勻時,與熱電偶的長度和直徑無關,只與熱電偶材料的成份和兩端的溫差有關。

  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國家標準規定了其熱電勢與溫度的關系、允許誤差、并有統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,一般也沒有統一的分度表,主要用于某些特殊場合的測量。

  爐管刀刃熱電偶冷端的溫度補償:
  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,為了節省熱電偶材料,降低成本,通常采用補償導線把熱電偶的冷端(自由端)延伸到溫度比較穩定的控制室內,連接到儀表端子上。
