Abstract

Disclosed is a scanner for frequency-analog passive resonators that are excited to oscillate at their natural frequency by electromagnetic, inductive or capacitive coupling or directly via a line, the frequency of the excitation signal following the natural frequency of the resonator in such a way that the difference between excitation frequency and natural frequency of the sensor is constant.
