4000系列 Capsuhelic液用差壓表-德威爾Dwyer
4000系列 Capsuhelic®液用差壓表可快速,準確地指示差壓,它能用于指示液體過濾器兩端的差壓,槽罐的液位,或用于其它任何需要正壓,負壓或差壓測量的場合。
采用了可靠耐用的Magnehelic&微差壓表的設計理念,結構簡單可靠,機芯無磨損,可精確讀數低到0.5英寸水柱,采用了密封膜盒,可在靜壓到500psig時,還可測出低于0.1英寸水拄的差壓。
精密的膜盒測量元件無需充液,可用于室外。可外部調整零點和量程,在校準或維護時,無需拆卸儀表。
注:可以用于氫氣,但在訂購時須選用Buna-N丁氰橡膠隔膜,工作壓力在35psi。
