Resonant pressure sensor, measurement assembly and associated aircraft

Abstract

A resonant pressure sensor (5) is proposed. The sensor comprises: - a support (6) having a base (7) surrounded by at least one wall (8, 9), - a deformable membrane (12) having a first face (13) configured to be subjected to the pressure to be measured and a second face (14) opposite the first face, the second face being connected to the support so that the support and the deformable membrane form a hermetically sealed cavity (15), the cavity being filled with a predetermined quantity of gas. The hermetically sealed cavity (15) comprises: - a temperature sensor (17) separate from the deformable membrane and configured to measure the temperature of the gas, and - a first beam (16) separate from the deformable membrane and having a first end (18) embedded in the wall and a second free end (19), the first beam being configured to measure the density of the gas.
