style="text-indent:25px">根據(jù)物體的全波長輻射能與溫度之間的關(guān)系來測量溫度，由光學(xué)系統(tǒng)、探測器、測量儀表和用于冷卻及煙塵防護(hù)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(yīng)信號可由測量儀表顯示或記錄。探測器通常采用響應(yīng)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(shí)間常數(shù)一般為秒級以上。此外熱電堆的基準(zhǔn)端溫度應(yīng)保持恒定或采取自動溫度補(bǔ)償措施。光學(xué)系統(tǒng)和探測元件對光譜輻射的響應(yīng)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(jì)也可稱為寬帶輻射溫度計(jì)。全輻射高溫計(jì)的優(yōu)點(diǎn)是結(jié)構(gòu)簡單、使用方便、性能穩(wěn)定、可以自動記錄和遠(yuǎn)距離傳送信號等。測溫范圍為100～2000℃,測溫誤差***值為8～12℃。遂寧溫度儀表批發(fā)</p><p
