    摘要: The invention relates to an ultrasonic displacement measurement system (1), which in particular can be used for hydraulic accumulators (3) having at least one movable separating element (5), which separates two media chambers (9, 11) from each other preferably in a media-tight manner within a housing (7), wherein the one media chamber (9) holds a compressible fluid or an incompressible fluid and the other media chamber (11) holds a compressible fluid, in particular in the form of a working gas, wherein the particular position of the movable separating element (5) within the housing (7) can be detected by means of at least one ultrasonic sensor (13), is characterized in that the at least one ultrasonic sensor (13) performs the position detection of the separating element (5) on the side of the other media chamber (11) having the compressible fluid. The invention further relates to a method for ultrasonic displacement measurement by means of such a system.

    摘要: A linear position sensing system includes a sensor, a conduit and an enclosure. The sensor has a connector and a converting element, where the connector includes a first end attached to the converting element and a second end that passes through the conduit and is configured for attachment to a moveable element of an external device. The enclosure houses the sensor. The conduit includes a first end fitting that is attached to the enclosure and a second end fitting that is affixed at a port or other aperture of the external device. The second end of the connector is configured to be inserted in the port other aperture and attached to the moveable element without disassembly of the external device.

    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.
