特性...

傳感范圍從真空到10,000 psi
耐用不銹鋼& Valox®外殼
應(yīng)用于高振動&高沖擊場合

概況/設(shè)計原理:

809系列壓力變送器專為工業(yè)應(yīng)用高性價比要求而特別設(shè)計，在典型工業(yè)場合可靠性強。809系列壓力變送器運行維護成本低，穩(wěn)壓直流供電，適用于大多數(shù)氣體和液體的溫度范圍。專門應(yīng)對惡劣環(huán)境的設(shè)計，使得該類產(chǎn)品適于高沖擊、高振蕩場合應(yīng)用。不銹鋼及Valox®外殼輕便小巧，易于合其他整體系統(tǒng)集合。809系列產(chǎn)品標(biāo)準特性使其在滿足極端環(huán)境條件苛刻要求的前提下，仍處在OEM廠商所青睞的經(jīng)濟價位下.

運行原理:

809系列傳感器采用成熟的中心安裝電極構(gòu)造，集合耐用型17-4PH不銹鋼壓力傳感元件共同構(gòu)成變?nèi)萜?。壓?或真空度)增大或減小時，電容隨之變化。獨立**輸出集成電路系統(tǒng)將電容變化轉(zhuǎn)換為完全可調(diào)的線性電壓或電流輸出信號.
