Measuring arrangement and measuring process for fluid pressure cylinders
Abstract:
A measuring arrangement for measuring the movement of a piston within a housing of a fluid cylinder includes a voltage generating arrangement for generating a reference voltage which is coupled to two locations of the cylinder which are spaced from each other in the direction of movement of the piston within the housing, these two locations being separately coupled to a piston movement evaluation arrangement which is also separately coupled to one or more further locations of the cylinder to which the two locations are electrically coupled so as to receive varying measurement voltage(s) as the two locations move relative to the further location(s). The evaluation arrangement uses the measurement voltage(s) to determine the piston movement.
