Agilent Varian 531 熱電偶真空壓力測量表管感測器,1/8 英吋 NPT 低碳鋼
Varian 零件號 F0472301


Agilent Varian 531 熱電偶表管感測器可連續準確地指示 1 x 10-3 torr 至 2.0 torr(1X10-3 mbar 至 2.7 mbar)的總壓力。專為粗加工和前置壓力測量而開發,將堅固的可靠性和出色的性能結合在一起。 Varian 531 熱電偶真空計是一種低成本壓力測量感測器。 Varian 531 熱電偶管感測器具有高抗振性,採用鍍鎳低碳鋼製成。 瓦里安零件號 F0472301

熱電偶真空壓力表,作者:Wikipedia.org
熱導率計依賴氣體導熱能力隨壓力降低的事實。在這種類型的壓力表中,透過電流流過燈絲來加熱燈絲。然後可以使用熱電偶或電阻溫度偵測器 (RTD) 來測量燈絲的溫度。此溫度取決於燈絲向周圍氣體散失熱量的速率,因此也取決於熱導率。一種常見的變體是皮拉尼真空計,它使用單根鉑絲作為加熱元件和 RTD。這些壓力計的準確度範圍為 20 Torr 至 10−3 Torr(取決於所購​​買的感測器和控制器的型號)。然而,它們對被測氣體的化學成分敏感,被稱為相對壓力測量方法,即它們根據氣體介質的導熱性能間接確定壓力。
