DA-7031-153-4|Dwyer波登管壓力開關
DS-7231-153-2|Dwyer波登管壓力開關
公認{zh0}壓力開關,Mercoid D 系列是世界上型號最全的壓力開關。只要你有應用需要,D 系列壓力開關都能滿足。D 系列具有非常高的靈敏性和穩(wěn)定性。DA 型帶有兩個外部調整件。一個可設置高壓工作點,另一個可設置低壓工作點。死區(qū)和高低設定點的差別,可以在整個標度內任意設定。DS 型帶有一個外部調整件,只提供一個設定點。死區(qū)由出廠時固定,不能現(xiàn)場改變。可選擇開關形式,密封的快速開關和密封的水銀開關。選項防爆防護,系列DAH - 等級Class I,Groups C And D;NEMA7; Class II,Groups E,F,G;Class III NEMA 9和9A,Division1。加“H” 在型號DA 或DS 后(量程15S 和16S 不提供)。
例如:DAH-31-153-7 . . ..FM 認證:對以上所列的普通用途和防爆型號的機構認證。加“F”在型號的DA,DS,DAH 或DSH 后。
例如:DAF-31-153-7 或DAHF-31-153-7其他選項(請向廠家咨詢):雙刀雙擲開關或其他開關類型,小范圍死區(qū)應用的固定死區(qū)水銀開關,手動復位操作,雙位操作,對于高振動和脈沖壓力的應用場合的Delrin? 襯套,防霉,虹吸管,膜片密封,法蘭安裝和遙控連接。
