分析MURR傳感器7000-40601-6300150的性能
主要應用:
溫度是表征物體冷熱程度的物理量,是工農業過程中一個很
高效率、節約能源、安全、促進國民經濟的發展起到非
重要而普遍的測量參數。溫度的測量及控制對產品質量、提
常重要的作用。由于溫度測量的普遍性,溫度傳感器的數量在各
種傳感器中居首位,約占50%
安裝不當引入的誤差:
如熱電偶安裝的位置及插入深度不能反映爐膛的真實溫度等, 換
句話說,熱電偶不應裝在太靠近門和加熱的地方,插入的深度至
空氣對流而影響測溫的準確性;熱電偶冷端太靠近爐體使溫度過
少應為保護管直徑的8~10倍;熱電偶的保護套管與壁間的間隔未
填絕熱物質致使爐內熱溢出或冷空氣侵入,因此熱電偶保護管和
熱電偶和動力電纜線裝在同一根導管內以免引入干擾造成誤差;
熱電偶不能安裝在被測介質很少流動的區域內,當用熱電偶測量
爐壁孔之間的空隙應用耐火泥或石棉繩等絕熱物質堵塞以免冷熱
100℃;熱電偶的安裝應盡可能避開強磁場和強電場,所以不應把
管內氣體溫度時,必須使熱電偶逆著流速方向安裝,而且充分與
氣體接觸。
