4000系列 Capsuhelic液用差压表-德威尔Dwyer

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。
