Abstract: A reflector reflects electromagnetic waves, which waves are emitted into a conducting structure from at least one antenna situated at a distance (d′) from the reflector. The distance (d′) is calculated based on measured emitted and reflected waves to and from the reflector, respectively. The reflector includes a reflector disc, an elongated body having a first longitudinal end and a second longitudinal end, the first longitudinal end being fastened to the reflector disc and the second longitudinal end being fastenable to an accumulator piston. Said elongated body further comprises at least two telescopically interconnected reflector tubes rendering reversible adjustment of the elongated body's longitudinal length around a predetermined equilibrium length possible. A piston accumulator applying the reflector, and a method for measuring the distance (d′) are also provided.

Abstract: The invention relates to a method for determining a position of a piston (5) in a piston pressure accumulator (1) and a ON correspondingly designed piston pressure accumulator (1). A housing (3) accommodates a displaceable piston (5). An electrode arrangement (15) having a plurality of 4-point measurement electrode pairs (17) is provided on the electrically conductive housing (3) and is designed to determine a position of the piston (5) inside the housing (3) by measuring a distribution of an electrical resistance or potential between inner electrodes (21) when a current is applied to outer electrodes (19), depending on a position along the housing (3). The position of the piston determined from the measurement of the potential distribution can be used to determine or check a charge state of the piston pressure accumulator (1).

Abstract: A hydraulic accumulator including a fluid chamber and a displaceable piston that is connected to a piston position-measuring means is disclosed. Embodiments of the hydraulic accumulator can provide a device that measures the available fluid volume in the accumulator. In embodiments, the displaceable part of the piston may separate fluid volume from gas volume, and may be connected to a wire that runs through the fluid volume and exits the outside of the accumulator through a sealed opening. Further, in embodiments, the wire may be led over pulleys and through a hollow member connected to the accumulator. The position of an associated metallic core member can be electrically monitored to provide position and fluid volume information.

Abstract: An apparatus for determining the weight of a payload in a bucket of a machine where the bucket is attached to a chassis of the machine by a linkage. The apparatus comprises an energy storage device for storing potential energy of the bucket, payload, and linkage when the bucket is moved from a first suspended position to a second suspended position. A mechanism provides physical data corresponding to a physical change in the energy storage device caused by storage of the potential energy and a processor calculates the weight of the payload using the physical data.

Abstract: A method of filling a pressure medium accumulator with a housing having an inner space that is subdivided into two chambers by a metallic pleated bellows used as a media-separating element. The first chamber thereof is filled with a gas and the second chamber is filled with a liquid pressure medium. The bottom valve is provided in a hydraulic port, its closing member being operable by the media-separating element. The valve permits filling of the second chamber with fluid and prevents a complete evacuation of the second chamber. To enable reliable filling of the above-mentioned chambers with corresponding media without damaging the pleated bellows, the method includes the steps of evacuating the second chamber, filling the second chamber with pressure medium and filling the first chamber with a gas.
