電子溫度探針的功能

溫度傳感器的工作原理是測量鉑元件的電阻變化：100 ohm = 0°C,138.4 ohm = 100°C。

在較小的溫度范圍內，溫度（T）與電阻（R）間的函數近似于直線：例如，假設0℃至100℃的溫度范圍內為直線，則50℃時的誤差為0.4℃。

為精確測量，須將電阻設為直線，以給出準確溫度。溫度標準（ITS-90）是對電阻與溫度間函數的定義。 圖示為直接測定觸頭電阻值的電阻與溫度間的函數，該函數通過實驗室試驗測得。我們建議設置補償熱耗散及電纜電阻的系統。

溫度變化1℃，電阻將變化0.384ohm，因此，測量電阻時，即便是出現小誤差，也可能導致溫度測量上的大誤差。

由于信號電平較低，須保持所有線纜遠離電纜、電動機、開關裝置及其它可能發出電噪聲的裝置。使用一端帶屏蔽裝置的屏蔽電纜，可減少干擾。

所用電纜較長時，須檢查測量裝置是否能控制該電纜的電阻。
