上海茂培供應(yīng) 4205/4210/4215/4220 差壓表/壓差表 Dwyer德威爾

4000系列 Capsuhelic?液用差壓表可快速，準(zhǔn)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(fù)壓或差壓測量的場合。

采用了可靠耐用的Magnehelic&微差壓表的設(shè)計(jì)理念，結(jié)構(gòu)簡單可靠，機(jī)芯無磨損，可精確讀數(shù)低到0.5英寸水柱，采用了密封膜盒，可在靜壓到500psig時(shí),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?？赏獠空{(diào)整零點(diǎn)和量程，在校準(zhǔn)或維護(hù)時(shí)，無需拆卸儀表。

注：可以用于氫氣，但在訂購時(shí)須選用Buna-N丁氰橡膠隔膜，工作壓力在35psi。
