2、插片式导线式连接方可供用户任意选定。
3、密封式不锈钢感应器安全可靠。
4、压力范围内可根据用户任意选定的压力值进行制造。
压力开关是与电器开关相结合的装置，当到达预先设定的流体压力时，开关接点动作。
主要应用于电厂、石化、冶金行业等工业设备上输出报警或控制信号，在工业领域中有着重要的用途，能预防生产工程中重要装置的损坏，避免了重大生产事故地发生。
 2.压力开关主要敏感元件2.1波纹管 特点:耐久性及耐振性较波登管好，接断差可调范围大，主要材质有不锈钢、磷青铜等，价格相对较高，但可测压力范围较小，*为40MPa(CB33)2.2膜片 电子压力开关是通过高精度仪表放大器放大压力信号，通过高速MCU采集并处理数据，内置精密传感器进行补偿，是检测压力、液位信号，实现压力、液位监测和控制的高精度设备。
广泛使用在化工、机械、水文、电力、环保等测量气体、液体压力的自动化系统中。
因为调节方便灵活，安装简单，可以替代大部分使用液位开关的场合。

它们的基本构成是壳体、带柱塞的安装套件、压缩弹簧、调节元件和微动开关。
如果要监测的压力低于调定值，则操作微动开关。
要监测的压力通过节流孔传到柱塞。
柱塞受弹簧座支持并克服压缩弹簧不断变化的作用力。
弹簧座将柱塞的运动传输到微动开关，并在达到调定压力时释放后者的压力。
这将打开或关闭电路，取决于电路的设置。
弹簧座的机械前挡块在压力突然降低和过压的情况下，可保护微动开关免于受到机械损伤，并防止压缩弹簧的过压。
要延长使用寿命，安装压力开关时应确保振动较小，使其免于受到液压冲击。

泵直接驱动，这种驱动系统的泵向液压缸提供高压工作液体，配流阀用来改变供液方向，溢流阀用来调节系统的限定压强，同时起安全溢流作用。
这种驱动系统环节少,结构简单,压强能按所需的工作力自动增减，减少了电能消耗，但须由液压机的大工作力和高工作速度来决定泵及其驱动电机的容量。
这种型式的驱动系统多用于中小型液压机，也有用泵直接驱动的大型（如120000千牛）自由锻造水压机。
