一、產(chǎn)品概述:
羅斯蒙特的2051C型壓力變送器為壓力丈量技術創(chuàng)立了一個新的規(guī)范。它具有無可比較的操作性能、靈敏的CoPlanarTM平臺,而且能夠晉級。新型2051C壓力變送器的性能指標保證了在不同工況下的精度和穩(wěn)定性。
二、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送給灌充液,接著灌充液將壓力傳送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(關于GP表壓變送器,大氣壓好像施加在傳感膜片的低壓側一樣)。AP差壓變送器,低壓側一直堅持一個參考壓力。傳感膜片的zui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(shù)字HART(高速可尋址遠程發(fā)送器數(shù)據(jù)公路)輸出信號。
三、2051變送器的應用
新型2051C的性能指標保證在不同工況下的精度和穩(wěn)定性。靈敏可變的CoPlanarTM平臺設計不但為您目前的應用需求提供合適的計劃,同時經(jīng)過PlantWeb工廠管控網(wǎng)和現(xiàn)場總線技術也完整能滿足您未來的技術請求。
