style="text-indent:25px">利用溫差電偶來測量溫度的溫度計。將兩種不同金屬導體的兩端分別連接起來，構成一個閉合回路，一端加熱，另一端冷卻，則兩個接觸點之間由于溫度不同，瀘州溫度儀表銷售，將產(chǎn)生電動勢，導體中會有電流發(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線，所接入的導線與接觸點的溫度都是均勻的，瀘州溫度儀表銷售，對原電動勢并無影響，瀘州溫度儀表銷售，通過測量溫差電動勢來求被測的溫度，這樣就構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%）構成的溫差電偶測溫可達千攝氏度以上；銥和銥銠（銠50%）可用在2300℃；若用鎢和鉬（鉬25%）則可高達2600℃。瀘州溫度儀表銷售</p><div

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波段。例如，采用硫化鉛時響應波長范圍約為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。瀘州溫度儀表銷售</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="瀘州溫度儀表銷售,溫度儀表"

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)理想氣體溫標為標準溫標。用氣體溫度計所測得的溫度和熱力學溫度相吻合。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><p style="text-indent:25px">根據(jù)物體的全波長輻射能與溫度之間的關系來測量溫度，由光學系統(tǒng)、探測器、測量儀表和用于冷卻及煙塵防護的輔助裝置組成。被測物體向傳感器方向發(fā)射的輻射經(jīng)過透鏡聚焦到探測元件上，所產(chǎn)生的相應信號可由測量儀表顯示或記錄。探測器通常采用響應波段較寬的熱電堆。為提高靈敏度，熱電堆往往需要由十幾支、幾十支的溫差電偶串聯(lián)組成，因而熱慣性較大，時間常數(shù)一般為秒級以上。此外熱電堆的基準端溫度應保持恒定或采取自動溫度補償措施。光學系統(tǒng)和探測元件對光譜輻射的響應有選擇性，不可能完全接收全波長的輻射，因此這種輻射溫度計也可稱為寬帶輻射溫度計。全輻射高溫計的優(yōu)點是結構簡單、使用方便、性能穩(wěn)定、可以自動記錄和遠距離傳送信號等。測溫范圍為100～2000℃,測溫誤差***值為8～12℃。</p><div
