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.
