NAGANO压力开关CQ30系列介绍
接触机构采用微动开关，是安全特性优异的压力开关。
该开关可在从低压到高压的广泛压力范围内制造，因此适用于液位控制、流量控制以及气动、液压和其他流体压力控制。
特征
･ 采用专为耐用压力开关而开发的波登管，并且适合振动。
･ 可以选择一接点类型或二接点类型。采用两种接点方式，可设定上限和下限。
･ 防酸涂层可防止因盐害而生锈。
This is a pressure switch with outstanding safety characteristics using a microswitch for contact mechanism.
This switch can be manufactured over a wide pressure range from low pressure to high pressure and is therefore suitable for liquid level control, flow control and also for pneumatic, hydraulic pressure and other fluid pressure controls.
Feature
･ Bourdon tube which was developed for durable pressure switch is used and is suitable for vibration.
･ The one contact type or two contact type can be selected. With the two contact type, the setting of upper limit and lower limit can be possible.
･ Acid-proof coating prevents rusting from salt damage.
