Abstract

The present invention relates to an oscillating sensor device (2), particularly for a proximity sensor, for sensing a dynamic change of attenuation caused by a measurable physical effect, comprising:- an oscillator including a resonance circuit (21) and an amplifier (22) fed back to the resonance circuit (21) and configured to maintain oscillation of the oscillator wherein the amplifier (22) comprises a non-linear gain characteristics defining an operating point at a preset amplitude of oscillation, and- a control unit (3) configured to control the open loop gain of the oscillator;wherein the control unit (3) is configured to control the open loop gain of the oscillator so that the operating point is set to a preset amplitude of the oscillation.
