Abstract

A device and a method to determine a position of a component that is moveable in a linear manner along an assigned axis are provided. A reference element that extends in a direction of the assigned axis is assigned to the component. The component may be brought into mechanical contact with the reference element. A respective piezo transducer is arranged on the reference element to generate and receive vibrations in a material used for the reference element.
