Title
(EN) DEVICE FOR MEASURING THE PRESSURE IN A GAS MEDIUM
(FR) INSTALLATION DE MESURE DE LA PRESSION D'UN MILIEU GAZEUX
Abstract
(EN)
Piezo-electric for measuring the pressure in a gas medium. Two flexure resonators (10, 11) facing each other are arranged in a substantially closed system under the influence of the gas to be measured. The measurement is carried out by determining the transmission factor of the first piezo-electric resonator (10) to the second piezo-electric resonator (1), the first piezo-electric resonator being excited in a predetermined way and the measuring signal being drawn from the second piezo-electric resonator (11).

Installation piézoélectrique pur mesurer la pression d'un milieu gazeux. Deux résonateurs de flexions (10, 11) se faisant force sont disposés dans un système largement fermé sous l'influence du gaz à mesurer. La mesure est effectuée par détermination du facteur de transfert du premier résonateur piézoélectrique (10) au second résonateur piézoélectrique (11), le premier résonateur piézoélectrique étant excité d'une manière définie et le signal de mesure étant tiré du second résonateur piézoélectrique (11).
