    • A switching mechanism includes a housing, an actuator retained within the housing, and an electrical switching apparatus. The actuator includes an actuation element retained by the housing, where at least a portion of the actuation element is positioned for receiving an actuation load, and a plunger substantially in contact with the actuation element and operable to translate when an actuation load is applied to the actuation element. A sealing element placed around a second cylindrical portion of the plunger contacts inner surfaces of the housing to provide a seal between a first end and second end of the housing. The actuator also includes a spring operable to apply a force to resist translation of the plunger. An electrical switching apparatus is retained by the second end of the housing.
    • 切换机构包括壳体,保持在壳体内的致动器以及电气开关装置。 所述致动器包括由所述壳体保持的致动元件,其中所述致动元件的至少一部分被定位成用于接收致动负载;以及柱塞,其基本上与所述致动元件接触并且可操作以在致动负载施加到所述致动元件时平移 致动元件。 围绕柱塞的第二圆柱形部分放置的密封元件接触壳体的内表面,以在壳体的第一端和第二端之间提供密封。 致动器还包括可操作以施加力以阻止柱塞平移的弹簧。 电气开关装置由壳体的第二端保持。

    • An electrical cordset for connecting a sensor connector used with a piston position sensor located within a high pressure environment and a control system. The cordset has a connector that is comprised of a housing having a cavity formed therein. A high pressure assembly having a plurality of pins is affixed and sealed to an opening in the housing such that inner ends of the pins are located within the cavity and the outer ends of the pins extend outwardly from the housing to be connected to the piston sensor. There is an electrical circuitboard within the cavity and the inner ends of the pins are electrically connected to the circuitboard.

    • A sensor mountable within a hydraulic cylinder provides a precision signal indicative of the position of the piston. The sensor includes a flexible connector attached between the cylinder piston and a converting element for sensing the piston displacement. The converting element comprises a pick-up spool, under tension, coupled to the other end of the connector and rotatable about an axis. A lead screw engages threads on the spool, and translates linearly when the spool rotates. A non-contacting electromechanical transducer senses the position of the lead screw, and provides an output signal proportional to the motion or position of the movable element. The transducer may be an LVDT or other transducer. A high-pressure seal assembly provides an electrical path between the sensor and an external connector. A piston stop prevents the piston from damaging the sensor. The sensor is held within the cylinder by port inserts threaded into standard cylinder hydraulic fluid ports and advanced inwardly to grip the sensor.
    • 可安装在液压缸内的传感器提供指示活塞位置的精确信号。 该传感器包括一个柔性连接器,其连接在气缸活塞和用于感测活塞位移的转换元件之间。 转换元件包括在张紧下连接到连接器的另一端并绕轴线转动的拾取线轴。 导螺杆接合线轴上的螺纹,并且当线轴旋转时线性平移。 非接触式机电换能器感测导螺杆的位置,并且提供与可移动元件的运动或位置成比例的输出信号。 换能器可以是LVDT或其他换能器。 高压密封组件提供传感器和外部连接器之间的电气路径。 活塞止挡件可防止活塞损坏传感器。 传感器通过插入标准气缸液压流体端口的端口插入件保持在气缸内,向内推进以夹紧传感器。
