摘要： A piston assembly for use in a gas spring or damper can include a piston rod partially positioned within a pressure tube, and a linear position sensing apparatus capable of tracking and determining the velocity of the piston rod. The linear position sensing apparatus can include a sensor, such as a waveguide sensor, connected to the piston rod such that the sensor moves with the piston rod. A beacon, such as a magnet, can be contained within the pressure tube and the sensor can detect the position of the beacon relative to the sensor.

摘要： A sensing device for a digital linear position sensor is disclosed. The sensing device may have a mounting device including a mounting surface. The sensing device may also have a plurality of resistors mounted on the mounting surface. The plurality of resistors may be electrically connected between a first voltage node (Uin) and a second voltage node (GND). Further, the sensing device may have a plurality of Hall switches mounted on the mounting surface at predetermined intervals in a longitudinal direction of the mounting device. Each of the plurality of Hall switches may be configured to adjust a total resistance of the plurality of resistors between the first voltage node (Uin) and the second voltage node (GND) upon actuation by an applied magnetic field.

摘要： A hydraulic actuator includes a hollow tube that has a first opening at a first end of the hollow tube and that has a second opening at a second end of the hollow tube. The hollow tube contains hydraulic fluid. A moveable magnet moves within hollow tube as a result of a magnetic field within the hollow tube. A magnetic field source located outside the hollow tube creates the magnetic field within the hollow tube. When the moveable magnet moves to the first end of the hollow tube, a first piston pushes hydraulic fluid out of the first opening. When the moveable magnet moves to the second end of the hollow tube a second piston pushes hydraulic fluid out of the second opening.

摘要： An actuator system includes a piston-cylinder arrangement including a piston that is movable with respect to a cylinder. A first flow path is in fluid communication with the piston-cylinder arrangement and a second flow path is in fluid communication with the piston-cylinder arrangement. A control system is operable to fluidly connect the first flow path to a source of high-pressure fluid and to connect the second flow path to a drain to move the piston in a first direction. A pressure sensor is fluidly connected to the first flow path and is operable to measure sufficient pressure data during the movement of the piston to generate a pressure versus time curve. The control system is operable to compare the generated pressure versus time curve to a known standard pressure versus time curve stored in the control system to determine the condition of the piston-cylinder arrangement.

摘要： A detecting unit detects a first output signal and a second output signal, which are output by a first sensor and a second sensor disposed on an actuator, and outputs a first detection signal and a second detection signal to a measurement unit. Based on the first detection signal and the second detection signal, the measurement unit measures a tact time taken for a piston to move from one end to another end of a movement range.

摘要： A piston rod defining a surface and including a structure on the surface configured to be traced by a position sensor during a stroke of the piston rod. The surface, and consequently the structure, are covered by a coating by buildup welding. The structure is produced in the same operation during the buildup welding of the coating. The entire structure may be formed by the buildup welding, or a coded basic profile is incorporated before the buildup welding.
