ABSTRACT:
A hybrid-coil linear displacement transducer including a base having recesses in which are distributed a primary coil and two secondary coils having a different number of turns, wound scarf-joint fashion, connected in series and in opposition and arranged, at least partially, facing the primary coil, a coupling core moving between the primary and the secondary coils so as to cause the voltages at the terminals of the transformer's secondary coils to vary, wherein the secondary coils consist of two windings made of two wires wound simultaneously, at least one of these two windings being connected in series to a third coil constituting the secondary of an additional transformer of which the primary is connected in series to the primary of the hybrid coil.
