Abstract
To provide a rugged vibration and shock-insensitive position transducer, a coil is wound on a lamella-like carrier which has a body element of electrically insulating material on which, at least on one surface, a foil of magnetically highly permeable material is positioned; these lamella-foil combinations can be stacked, or a unitary body which foils on both sides can be provided. A short-circuit ring, movable along the core, changes the inductance of the coil wound thereon, the value of which can be determined by energizing the coil with alternating current.
