摘要： Apparatus for the determination of the location and/or distance traveled by a piston in a cylinder. This apparatus can easily be integrated into shock absorbers, vibration dampers and pneumatic springs, and exhibits a high degree of insensitivity to at least electrical interference, therefore being particularly well-suited for operation under unfavorable ambient conditions. As a result of the use of the most modern semiconductor technology and a suitable geometric arrangement, a very good resolution can be achieved, along with an automatic recognition of the direction of piston travel. Such an apparatus has a number of semiconductor elements; in one embodiment, in a beam fastened inside the cylinder or, in another embodiment, in the hollow piston rod. These semiconductor elements are arranged so that, over the axial length of the piston stroke, the distances between two neighboring semiconductor elements correspond to a specified measurement value resolution. The semiconductor elements are connected with an electronic calculating or computing system, and the component opposite the semiconductor elements is an electrode which generates an electric field. This electrode is connected in operation to a source of electrical voltage or a ground.

摘要： A master brake cylinder arrangement includes at least one piston arrangement with a piston movably guided in a receiving bore in a master brake cylinder housing. The piston, together with the receiving bore, delimits a pressure chamber which is in fluid connection with a hydraulic brake circuit and may be moved along a movement axis between an initial position and an actuation position. A position detecting device detects movement of the piston caused by actuation is provided within the receiving bore. The position detecting device has a sensor element, which is movable as a function of a piston movement, and a position detecting sensor, which is arranged fixed on the master brake cylinder housing. The sensor element is received and guided in the master brake cylinder housing independently of the piston and is capable of interacting with the piston for deflection as a function of the piston movement.

摘要： A hydraulic excavator includes a base body portion, a movable portion, a hydraulic cylinder, a position sensor, a rotary encoder, and a control unit. The rotary encoder includes a light emitting unit, a light receiving unit, and a disk unit having a plurality of transmission portions. The control unit measures the stroke length of the hydraulic cylinder by correcting deviation of the stroke length, which is measured by the position sensor, based on the pulse signal output from the rotary encoder. In this way, there can be obtained a hydraulic excavator capable of precisely measuring a stroke length of a hydraulic cylinder driving a work implement, as well as a method for measuring the stroke of the hydraulic cylinder of the hydraulic excavator.
