簡介
工業(yè)用薄膜鉑熱電阻作為新一代的溫度測量和調(diào)節(jié)傳感器，通常用來和顯示儀表等配套，以直接測量各種生產(chǎn)過程中-79℃～600℃范圍內(nèi)液體，蒸汽和氣體介質(zhì)及固定表面等溫度。
技術(shù)參數(shù)
熱電阻感溫元件在0℃的電阻值（R0）
分度號Pt100 B級 R0=100±0.12Ω
鉑熱電阻的電阻與溫度關(guān)系一般可用以下關(guān)系表示：在-79～0℃范圍內(nèi)
Rt=R0｛1+At+Bt2+C(t-100℃)t3｝
Rt=R0(1+At+Bt2)
Rt 為t℃時熱電阻的電阻值（Ω）
式中的R0為0℃時熱電阻的電阻值（Ω）
t為被測介質(zhì)溫度（℃）
A、B、C等均為有關(guān)的分度常數(shù)
