NAGANO KEIKI压力开关CQ21系列介绍及选型
这是一种结构简单的压力开关，其中波登管应用于压力传感元件，其移动直接作用于微动开关。这些压力开关有很多是为过程工业的报警和控制而制造的，其中很多开关在发电厂和化工厂有应用效果。
根据波登管移动直接作用于微动开关的结构，构成部件的数量少并且表现出优异的耐用性。
压力范围从低压扩展到高压：0.1 MPa 到 70 MPa，符合广泛的范围。
该压力开关主要针对火力发电厂开发，接线空间大，维护方便。
This is a pressure switch with simple construction in which a Bourdon tube is applied to the pressure sensing element and its move directly functions the microswitch. A lot of these pressure switches have been manufactured for the warning and control of process industry, and a lot of these switches have application results in power and chemical plants.
According to the construction by which a Bourdon tube move directly functions the microswitch, the number of constituent parts is small and excellent durability is demonstrated.
The pressure range extends extensively from low pressure to high pressure:0.1 MPa to 70 MPa, complying with extensive ranges.
This pressure switch has been developed mainly for thermal power stations, equipped with a large wiring space, assuring easy maintenance work.
