上海茂培供应 4205/4210/4215/4220 差压表/压差表 Dwyer德威尔

4000系列 Capsuhelic?液用差压表可快速，准确地指示差压，它能用于指示液体过滤器两端的差压，槽罐的液位，或用于其它任何需要正压，负压或差压测量的场合。

采用了可靠耐用的Magnehelic&微差压表的设计理念，结构简单可靠，机芯无磨损，可精确读数低到0.5英寸水柱，采用了密封膜盒，可在静压到500psig时,还可测出低于0.1英寸水拄的差压。

精密的膜盒测量元件无需充液，可用于室外。可外部调整零点和量程，在校准或维护时，无需拆卸仪表。

注：可以用于氢气，但在订购时须选用Buna-N丁氰橡胶隔膜，工作压力在35psi。
