Abstract
A measuring system including: at least two electromechanical resonators each having a resonant frequency varying around an offload resonant frequency according to a physical quantity to be measured; at least one reading device connected to inputs of the resonators and configured to supply an excitation signal on the inputs; and a memory in which is recorded, for each resonator, offload resonance information relating to the offload resonant frequency of the resonator. Each reading device is configured to determine the resonant frequency of one or more resonators selected for reading by configuring at least one element of the reading device using the offload resonance information stored for each selected resonator.
