Abstract

A hydraulic component for vehicles, such as for maritime applications, is a hydraulic cylinder-piston unit. The piston of the hydraulic component has a piston rod with a measurement section. A magnetic rod in the piston rod extends over the measurement section. The magnetic rod has a helically varied magnetic field direction. The hydraulic component includes a sensor device having a scanning region measuring the field direction. The sensor device is arranged such that, over the entire stroke path of the piston, at least a part of the magnetic rod is located in the scanning region. The sensor device has a sensor unit configured to transmit measurement results for the field direction to a processing unit, configured to process and output the measurement results. Furthermore, the present invention relates to a hydraulic adjustment system having at least one hydraulic component and a vehicle having at least one hydraulic adjustment system.
