Abstract
An inductive sensor is proposed which comprises at least one resonant circuit, an evaluation device which in a measuring phase evaluates oscillations of the at least one resonant circuit for generating sensor signals, an energy storage device, and a transfer device which in a relaxation phase of the at least one resonant circuit stores oscillation energy of the at least one resonant circuit in the energy storage device.

Inductive sensor, comprising:
- a resonant circuit;
- an evaluation device which in a measuring phase evaluates oscillations of the at least one resonant circuit for generating sensor signals;
- an energy storage device;
- a transfer device which in a relaxation phase of the at least one resonant circuit stores oscillation energy of the at least one resonant circuit in the energy storage device;
- and
- a voltage increasing device which in the relaxation phase effects a voltage increase in comparison to the measuring phase;
- wherein the relaxation phase follows the measuring phase with decaying oscillations.
