美國艾默生旗下的(Rosemount)羅斯蒙特變送器為壓力測量技術(shù)創(chuàng)建了一個(gè)新的標(biāo)準(zhǔn)。羅斯蒙特3051CD差壓變送器是羅斯蒙特變送器里的智能差壓變送器。羅斯蒙特3051壓力變送器具有*的操作性能、靈活的CoPlanarTM平臺(tái),而且可以升級。新型羅斯蒙特3051變送器的性能指標(biāo)保證了在不同工況下的精度和穩(wěn)定性。
羅斯蒙特3051變送器工作原理
工作時(shí),高、低壓側(cè)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(gè)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(cè)一樣)。低壓側(cè)始終保持一個(gè)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(cè)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(zhuǎn)換為相應(yīng)的電流,電壓或數(shù)字HART(高速可尋址遠(yuǎn)程發(fā)送器數(shù)據(jù)公路)輸出信號(hào)??梢酝ㄟ^羅斯蒙特475手操器對其進(jìn)行現(xiàn)場和遠(yuǎn)程通訊。
羅斯蒙特3051差壓變送器的應(yīng)用
新型羅斯蒙特3051CD差壓變送器的性能指標(biāo)保證在不同工況下的精度和穩(wěn)定性。靈活可變的CoPlanarTM平臺(tái)設(shè)計(jì)不但為您目前的應(yīng)用需求提供*方案,同時(shí)通過PlantWeb工廠管控網(wǎng)和現(xiàn)場總線技術(shù)也完*滿足您將來的技術(shù)要求。小巧而質(zhì)輕的共面設(shè)計(jì),具有*性能,對現(xiàn)場的庫存要求zui低,是進(jìn)口壓力變送器中的*。3051差壓變送器采用301/305/306閥組,可節(jié)約安裝費(fèi)用20%以上。因?yàn)榱_斯蒙特公司可將Rosemount變送器/閥組在工廠一體化安裝。
美國Rosemount(羅斯蒙特)3051壓力變送器,工業(yè)領(lǐng)域中*的壓力測量產(chǎn)品。目前在世界上有四個(gè)工廠提供原裝3051變送器,向中國供貨的為北京遠(yuǎn)東羅斯蒙*限公司和新加坡羅斯蒙特私人有限公司。
