在冷端采取一定措施補(bǔ)償由于冷端溫度變化造成的影響稱為熱電偶的冷端補(bǔ)償正常。與測(cè)量儀表連接用**補(bǔ)償導(dǎo)線。是一種感溫元件，是一種一次儀表，熱電偶直接丈量溫度。由2種不同成分材質(zhì)的導(dǎo)體組成的閉合回路，由于材質(zhì)不同，不同的電子密度產(chǎn)生電子擴(kuò)散，穩(wěn)定均衡后就產(chǎn)生了電勢(shì)。當(dāng)兩端存在梯度溫度時(shí)，回路中就會(huì)有電流產(chǎn)生，產(chǎn)生熱電動(dòng)勢(shì)，溫度差越大，電流就會(huì)越大。測(cè)得熱電動(dòng)勢(shì)之后即可曉得溫度值。熱電偶實(shí)際上是一種能量轉(zhuǎn)換器，可將熱能轉(zhuǎn)換成電能。熱電偶的技術(shù)優(yōu)勢(shì)：熱電偶測(cè)溫范圍寬，性能比擬穩(wěn)定；丈量精度高，熱電偶與被測(cè)對(duì)象直接接觸，不受中間介質(zhì)的影響；熱響應(yīng)時(shí)間快，熱電偶對(duì)溫度變化反響靈活；丈量范圍大，熱電偶從-40~+1600℃均可連續(xù)測(cè)溫；熱電偶性能牢靠，機(jī)械強(qiáng)度好。運(yùn)用壽命長，裝置便當(dāng)。電偶必需是由兩種性質(zhì)不同但契合一定要求的導(dǎo)體（或半導(dǎo)體）材料構(gòu)成回路。熱電偶丈量端和參考端之間必需有溫差。將兩種不同資料的導(dǎo)體或半導(dǎo)體A和B焊接起來，構(gòu)成一個(gè)閉合回路。當(dāng)導(dǎo)體A和B的兩個(gè)執(zhí)著點(diǎn)1和2之間存在溫差時(shí)，兩者之間便產(chǎn)生電動(dòng)勢(shì),因此在回路中構(gòu)成一個(gè)大小的電流,這種現(xiàn)象稱為熱電效應(yīng)。熱電偶就是應(yīng)用這一效應(yīng)來工作的。</p><div
