Abstract (en)
[origin: EP1217221A2] The pressure fluid cylinder (1) has a piston (3) with a piston rod (4) having differently magnetized areas acting as indicators (6). Sensors (10) detect outward movement of the magnetized areas to determine the piston rod position. The indicator can be formed by a magnetized rod inserted into a bore in the piston rod.
