<p>The inductive proximity sensor is provided with an LC oscillating circuit excited by electric pulses and which can be damped by the approach of an electrically conductive object, as well as with an evaluation circuit (33, 34) for determining the oscillation damping caused by the damping element. The inductivity of the LC oscillation circuit is produced by the primary winding (L1) of a transformer, the secondary winding (L2) of which has a larger number of turns than the primary winding (L1). The evaluation circuit (33, 34) is located in the circuit of the secondary winding (L2).</p> |
