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。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(kuò)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，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(jī)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(kuò)展至常溫范圍。瀘州溫度儀表推薦</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="瀘州溫度儀表推薦,溫度儀表"

style="text-indent:25px">利用溫差電偶來測量溫度的溫度計。將兩種不同金屬導(dǎo)體的兩端分別連接起來，構(gòu)成一個閉合回路，一端加熱，另一端冷卻，則兩個接觸點之間由于溫度不同，將產(chǎn)生電動勢，導(dǎo)體中會有電流發(fā)生。因為這種溫差電動勢是兩個接觸點溫度差的函數(shù)，所以利用這一特性制成溫度計。若在溫差電偶的回路里再接入一種或幾種不同金屬的導(dǎo)線，所接入的導(dǎo)線與接觸點的溫度都是均勻的，對原電動勢并無影響，通過測量溫差電動勢來求被測的溫度，這樣就構(gòu)成了溫差電偶溫度計。這種溫度計測溫范圍很大。例如，銅和康銅構(gòu)成的溫差電偶的測溫范圍在200～400℃之間；鐵和康銅則被使用在200～1000℃之間；由鉑和鉑銠合金（銠10%）構(gòu)成的溫差電偶測溫可達(dá)千攝氏度以上；銥和銥銠（銠50%）可用在2300℃；若用鎢和鉬（鉬25%）則可高達(dá)2600℃。瀘州溫度儀表推薦</p><p
