羅斯蒙特的3051C壓力變送器為壓力測量技術創建了一個新的標準。羅斯蒙特3051壓力變送器具有無可比擬的操作性能、靈活的CoPlanarTM平臺，而且可以升級。新型羅斯蒙特3051C壓力變送器的性能指標保證了在不同工況下的精度和穩定性。

工作原理：工作時，高、低壓側的隔離膜片和灌充液將過程壓力傳遞給灌充液，接著灌充液將壓力傳遞到傳感器中心的傳感膜片上。傳感膜片是一個張緊的彈性元件，其位移隨所受壓而變化（對于GP表壓變送器，大氣壓如同施加在傳感膜片的低壓側一樣）。AP絕壓變送器，低壓側始終保持一個參考壓力。傳感膜片的更大位移量為0.004英寸（0.1毫米），且位移量與壓力成正比。兩側的電容極板檢測傳感膜片的位置。傳感膜片和電容極板之間電容的差值被轉換為相應的電流，電壓或數字HART（高速可尋址遠程發送器數據公路）輸出信號。
