Title (EN) MEASURING SYSTEM HAVING ELECTROMECHANICAL RESONATORS, METHOD FOR MANUFACTURING SUCH A SYSTEM, AND METHOD FOR READING AT LEAST TWO RESONATORS
(FR) SYSTEME DE MESURE A RESONATEURS ELECTROMECANIQUES, PROCEDE DE FABRICATION D'UN TEL SYSTEME ET PROCEDE DE LECTURE D'AU MOINS DEUX RESONATEURS ELECTROMECANIQUES
Abstract:
(EN) The invention relates to a measuring system having electromechanical resonators, comprising at least two electromechanical resonators (1021...102N) which each have a resonance frequency that varies around a vacuum resonance frequency depending on a physical quantity to be measured, and at least one reading device (110) connected to the inputs of the resonators and designed to supply an energizing signal to said inputs. The system further comprises a memory (120) in which, for each resonator, vacuum resonance data pertaining to the vacuum resonance frequency of the resonator is recorded, and each reading device (110) is to determine the resonance frequency of one or more resonators selected for reading by configuring at last one element of the reading device (110) from the vacuum resonance data stored for each selected resonator.
(FR) Système de mesure à résonateurs électromécaniques, comportant au moins deux résonateurs électromécaniques (1021...102N) présentant chacun une fréquence de résonance variant autour d'une fréquence de résonance à vide en fonction d'une grandeur physique à mesurer, et au moins un dispositif de lecture (110) connecté aux entrées des résonateurs et conçu pour fournir un signal d'excitation sur lesdites entrées. Le système comporte en outre une mémoire (120) dans laquelle est enregistrée, pour chaque résonateur, une information de résonance à vide relative à la fréquence de résonance à vide du résonateur, et chaque dispositif de lecture (110) est destiné à déterminer la fréquence de résonance d'un ou plusieurs résonateurs sélectionnés pour lecture en configurant au moins un élément du dispositif de lecture (110) à partir de l'information de résonance à vide mémorisée pour chaque résonateur sélectionné.
