一體化溫度變送器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(cè)溫度的變化，在進(jìn)行快速測(cè)量時(shí)這種影響尤為突出，因此應(yīng)盡可能采用熱電極較細(xì)、保護(hù)管直徑較小的熱電偶。在測(cè)溫環(huán)境許可時(shí)，甚至可將保護(hù)管取去。由于存在測(cè)量滯后，用熱電偶檢測(cè)出的溫度波動(dòng)的振幅較爐溫波動(dòng)的振幅小。為了準(zhǔn)確的測(cè)量溫度，應(yīng)當(dāng)選擇時(shí)間常數(shù)小的熱電偶，時(shí)間常數(shù)與傳熱系數(shù)成反比，與熱電偶熱端的直徑、材料的密度及比熱成正比，如要減小時(shí)間常數(shù)，除增加傳熱系數(shù)以外，有效的辦法是盡量減小熱端的尺寸。

一般Ni-Cr絲用得多，因?yàn)镹i-Cr絲抗氧化性強(qiáng)，熱穩(wěn)定性能好。為了保證激發(fā)輻射條件穩(wěn)定，要求加熱燈絲的電流應(yīng)經(jīng)穩(wěn)壓電源供給，如果電流改變，燈絲溫度也要相應(yīng)地變化，這將造成光譜波長輻射能量的改變。光源輻射能量的大部應(yīng)集中在待測(cè)組分特征波長范圍內(nèi)，即輻射的特征波長必須符合CO2和SO2的特征波長，這樣可以增加待測(cè)組分對(duì)能量的吸收，大大提高測(cè)量的靈敏度。。它是經(jīng)特殊加工的鍍金反射鏡，并將光源的輻射光反射成一束平行光。對(duì)發(fā)展真空干燥設(shè)備的幾點(diǎn)看法1)創(chuàng)新是發(fā)展真空干燥設(shè)備的根本出路目前真空干燥設(shè)備發(fā)展較慢，有1個(gè)重要的原因是互相仿制，在同一技術(shù)水平上徘徊，缺乏創(chuàng)新。仿制的能力強(qiáng)，速度快，創(chuàng)新的觀念差，投入少。把競爭的精力放在了搶市場(chǎng)，拉關(guān)系，價(jià)格戰(zhàn)方面。好一點(diǎn)的作法是在質(zhì)量上和售后服務(wù)上，下了一些功夫。但這些都不是發(fā)展真空干燥設(shè)備的好方法，必須投入人力、物力、財(cái)力去創(chuàng)新。節(jié)能是發(fā)展真空干燥設(shè)備的關(guān)鍵能源緊缺已經(jīng)受到了全世界的關(guān)注，傳統(tǒng)觀念都認(rèn)為真空干燥設(shè)備的能耗高，原因是它需要加真空泵。
