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(xué)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(dǎo)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，眉山溫度儀表供應(yīng)。如采用硅光電池，則響應(yīng)波段約為0.4～1.1微米，眉山溫度儀表供應(yīng)，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(yuǎn)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，眉山溫度儀表供應(yīng)，測量下限低，可測量微小目標(biāo)，而且比較窄的敏感譜帶可以減少或消除在瞄準(zhǔn)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。眉山溫度儀表供應(yīng)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="眉山溫度儀表供應(yīng),溫度儀表"

style="text-indent:25px">雙金屬溫度計：雙金屬溫度計是一種測量中低溫度的現(xiàn)場檢測儀表。可以直接測量各種生產(chǎn)過程中的-80℃~+500℃范圍內(nèi)液體蒸汽和氣體介質(zhì)溫度。雙金屬溫度計的工作原理是利用二種不同溫度膨脹系數(shù)的金屬，為提高測溫靈敏度，通常將金屬片制成螺旋卷形狀，當(dāng)多層金屬片的溫度改變時，各層金屬膨脹或收縮量不等，使得螺旋卷卷起或松開。由于螺旋卷的一端固定而另一端和一可以自由轉(zhuǎn)動的指針相連，因此，當(dāng)雙金屬片感受到溫度變化時，指針即可在一圓形分度標(biāo)尺上指示出溫度來。</p><p style="text-indent:25px">氣體溫度計：利用一定質(zhì)量的氣體作為工作物質(zhì)的溫度計。用氣體溫度計來體現(xiàn)理想氣體溫標(biāo)為標(biāo)準(zhǔn)溫標(biāo)。用氣體溫度計所測得的溫度和熱力學(xué)溫度相吻合。氣體溫度計是在容器里裝有氫或氮氣（多用氫氣或氦氣作測溫物質(zhì)，因為氫氣和氦氣的液化溫度很低，接近于***零度，故它的測溫范圍很廣），它們的性質(zhì)可外推到理想氣體。這種溫度計有兩種類型：定容氣體溫度計和定壓氣體溫度計。定容氣體溫度計是氣體的體積保持不變，壓強隨溫度改變。定壓氣體溫度計是氣體的壓強保持不變，體積隨溫度改變。</p><div
