    • A hydraulic cylinder assembly includes a transducer having a wand and a wiper assembly, wherein the wiper assembly is positioned a predetermined distance from an end of the wand for providing a desired startup resistance. A tube includes a piston contained therein for actuation between the first end of the tube and the second end of the tube. A rod is operatively attached to the piston. The piston and the rod are movable together between the first and second ends of the tube. The second end of the tube includes the transducer for monitoring the position of the piston with respect to the second cap member. The wand extends into the piston, and the transducer senses the position of the wiper assembly with respect to the wand for monitoring the position of the piston with respect to the second cap member.
    • 液压缸组件包括具有杆和刮水器组件的换能器,其中擦拭器组件定位在与杆的端部预定距离处以提供期望的起动阻力。 管包括其中包含的活塞,用于在管的第一端和管的第二端之间的致动。 杆可操作地附接到活塞。 活塞和杆可在管的第一和第二端之间一起移动。 管的第二端包括用于监测活塞相对于第二盖构件的位置的换能器。 该魔杖延伸到活塞中,并且换能器感测擦拭器组件相对于杆的位置,用于监测活塞相对于第二帽构件的位置。
