Abstract
A converter includes a feed source furnishing a medium-frequency feed voltage of constant frequency and amplitude, a coupling element and a scanning head for producing an output signal as a function of a position of the coupling element relative to the scanning head. The scanning head includes a shell core of magnetic material having a middle leg and a cup-shaped jacket concentrically surrounding the middle leg, the cup-shaped jacket having an outer surface; a primary winding being wound around the outer surface of the jacket and connected to the feed source; and a secondary winding wound around the middle leg. The primary winding and the secondary winding are connected in opposite directions in series for supplying alternating voltages at the windings forming a differential voltage having a phase relationship relative to the feed voltage determining the output signal. A load having constant, accurately reproducible properties is coupled to the magnetic flux by means of the middle leg.
