Magnetostrictive position sensor utilizing the propagation time principle

摘要

The position sensor has a waveguide (3), an associated detector coil (5) and a position element, e.g. a position magnet (28) which is displaced along the waveguide. The central part of the waveguide between the detection region (105) and the opposing free end lies within a hollow return conductor (3*) of an electrically conductive non-magnetic material.
