1、測(cè)量精度和溫度測(cè)量范圍的選擇使用溫度在1300~1800℃，要求精度又比較高時(shí)，一般選用B型熱電偶；要求精度不高，氣氛又允許可用鎢錸熱電偶，高于1800℃一般選用鎢錸熱電偶；使用溫度在1000~1300℃要求精度又比較高可用S型熱電偶和N型熱電偶；在1000℃以下一般用K型熱電偶和N型熱電偶，低于400℃一般用E型熱電偶；250℃下以及負(fù)溫測(cè)量一般用T型電偶，在低溫時(shí)T型熱電偶穩(wěn)定而且精度高。 2、使用氣氛的選擇 S型、B型、K型熱電偶適合于強(qiáng)的氧化和弱的還原氣氛中使用，J型和T型熱電偶適合于弱氧化和還原氣氛，若使用氣密性比較好的保護(hù)管，對(duì)氣氛的要求就不太嚴(yán)格。 3、耐久性及熱響應(yīng)性的選擇線(xiàn)徑大的熱電偶耐久性好，但響應(yīng)較慢一些，對(duì)于熱容量大的熱電偶，響應(yīng)就慢，測(cè)量梯度大的溫度時(shí)，在溫度控制的情況下，控溫就差。要求響應(yīng)時(shí)間快又要求有一定的耐久性，選擇鎧裝偶比較合適。 4、測(cè)量對(duì)象的性質(zhì)和狀態(tài)對(duì)熱電偶的選擇運(yùn)動(dòng)物體、振動(dòng)物體、高壓容器的測(cè)溫要求機(jī)械強(qiáng)度高，有化學(xué)污染的氣氛要求有保護(hù)管，有電氣干擾的情況下要求絕緣比較高。</p><div style="width:100%;text-align: center;"><img
