Abstract
A compensated temperature distance detector wherein the detecting coil is realized in the form of wires, divided and isolated the one from the others. A first set of wires (L) constitutes the oscillating coil parallel connected to a capacitor and fed between two distinct voltages (VCC and M) through a current source (IB) and a second set of wires (L'), connected at a first extremity to a first set of wires and to a generator, is connected at its other extremity to a third voltage (V1), whereby a d.c. current flows through the series connection of the first and second sets of wires.
