力士乐压力继电器是利用液体的压力来启闭电气触点的液压电气转换元件。当系统压力达到压力继电器的调定值时，发出电信号，使电气元件（如电磁铁、电机、时间继电器、电磁离合器等）动作，使油路卸压、换向，执行元件实现顺序动作，或关闭电动机使系统停止工作，起安全保护作用等。压力继电器有柱塞式、膜片式、弹簧管式和波纹管式四种结构形式。 现货力士乐压力继电器REXROTH上海、江苏优势供应商
力士乐压力继电器的工作原理作介绍：
当从继电器下端进油口3进入的液体压力达到调定压力值时，推动柱塞2上移，此位移通过杠杆放大后推动微动开关4动作。改变弹簧1的压缩量，可以调节继电器的动作压力。
应用场合：用于安全保护、控制执行元件的顺序动作、用于泵的启闭、用于泵的卸荷。
注意： 压力继电器必须放在压力有明显变化的地方才能输出电信号。若将压力继电器放在回油路上，由于回油路直接接回油箱，压力也没有变化，所以压力继电器也不会工作。
