机械式可调压力开关0-400bar
                                     PS21系列

                                            原理，结构
                                            压力开关使用膜片式传感器，耐高压，使用寿命长，结构紧凑，体积小。
                                            由于压力开关采用特殊的传感器结果，解决了活塞式压力开关常见的漏油缺陷。

                                            特点

                                            这些小巧型的压力开关是OEM应用设计的，他们是工程机械
                                            船用阀门遥控系统等.要求高耐压设备的理想选择。
