因此熱電偶保護(hù)管和爐壁孔之間的空隙應(yīng)用耐火泥或石棉繩等絕熱物質(zhì)堵塞以免冷熱空氣對流而影響測溫的準(zhǔn)確性；熱電偶冷端太靠近爐體使溫度超過100℃；熱電偶的安裝應(yīng)盡可能避開強(qiáng)磁場和強(qiáng)電場，所以不應(yīng)把熱電偶和動力電纜線裝在同一根導(dǎo)管內(nèi)以免引入干擾造成誤差；熱電偶不能安裝在被測介質(zhì)很少流動的區(qū)域內(nèi)，當(dāng)用熱電偶測量管內(nèi)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。2、絕緣變差而引入的誤差如熱電偶絕緣了，保護(hù)管和拉線板污垢或鹽渣過多致使熱電偶極間與爐壁間絕緣不良，在高溫下更為嚴(yán)重，這不僅會引起熱電勢的損耗而且還會引入干擾，由此引起的誤差有時可達(dá)上百度。3、熱惰性引入的誤差由于熱電偶的熱惰性使儀表的指示值落后于被測溫度的變化，在進(jìn)行快速測量時這種影響尤為突出。所以應(yīng)盡可能采用熱電極較細(xì)、保護(hù)管直徑較小的熱電偶。測溫環(huán)境許可時，甚至可將保護(hù)管取去。由于存在測量滯后，用熱電偶檢測出的溫度波動的振幅較爐溫波動的振幅小。測量滯后越大，熱電偶波動的振幅就越小，黑龍江鑄造熱電偶保護(hù)管零售，與實(shí)際爐溫的差別也就越大，黑龍江鑄造熱電偶保護(hù)管零售。當(dāng)用時間常數(shù)大的熱電偶測溫或控溫時，儀表顯示的溫度雖然波動很小，黑龍江鑄造熱電偶保護(hù)管零售，但實(shí)際爐溫的波動可能很大。為了準(zhǔn)確的測量溫度。</p><div
