Magnetostrictive transducers are used for position measurement. The sensors are especially used to measure the stroke of hydraulic cylinders. Their cylindrical design predestines magnetostrictive transducers for industrial application and the installation in hydraulic cylinders. Magnetostrictive hydraulic sensors are used in packing machines, plastic machines, steel rolls or in beverage bottling plants.
In workshops or in the automobile production cars are lifted for work on the substructure. This is usually done by hydraulic lifts. Hydraulic cylinders installed in the lifts hoist the cars. The stroke movement are measured by magnetostrictive transducers. The position measurement is especially important in automatized processes.
Magnetostrictive transducers - lift bridges
Lift bridges are built over busy waterways. These lift up when a ship wants to drive through the waterway. For this a bridge part is raised by means of hydraulic cylinders so far that the ship can easily pass underneath the lifted bridge.
Magnetostrictive transducers are installed inside the hydraulic cylinders. The sensors measure the stroke and transmit the values to a control unit. The hydraulic sensors ensure that the bridge part reaches the minimum height to let the ship pass.
