style="text-indent:25px">利用被測物體的部分波段輻射能與溫度之間的關(guān)系來測量物體溫度，又稱窄帶輻射溫度計。部分輻射高溫計由某一較窄響應(yīng)波段的光學系統(tǒng)和探測元件組成。被測物體的部分熱輻射經(jīng)調(diào)制盤和濾**后照到探測元件上,再經(jīng)放大由儀表顯示或記錄。探測元件通常采用光導型或光生伏打型，它們決定傳感器的響應(yīng)波段。例如，采用硫化鉛時響應(yīng)波長范圍約為0.6～3.0微米，時間常數(shù)為毫秒量級。如采用硅光電池，則響應(yīng)波段約為0.4～1.1微米，時間常數(shù)可至微秒量級。采用紅外輻射探測技術(shù)還可使輻射測溫范圍向低溫擴展。部分輻射高溫計有多種形式，如遠程紅外測溫儀、紅外線光源探測儀、紅外線亮度測溫儀、光電溫度計等。這類傳感器的優(yōu)點是響應(yīng)速度快，測量精度高，穩(wěn)定性好，測量下限低，可測量微小目標，而且比較窄的敏感譜帶可以減少或消除在瞄準光路中由于氣體的吸收和發(fā)射率所造成的不良影響。部分輻射高溫計常用于測量靜止或運動的灼熱體表面溫度，如測量生產(chǎn)中的鋼板、鍍錫鐵皮、快速加工件、電機或電纜接頭溫度等。一般測溫范圍為 100～1500℃，采用紅外探測元件時可擴展至常溫范圍。樂山溫度儀表廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="樂山溫度儀表廠家,溫度儀表"
