The invention concerns a gyroscopic sensor comprising a resonator (14) having the shape of a bell or a revolving dome, fixed along its axis and having a circular rim located in a plane perpendicular to the axis, spaced apart from the resonator fixing point in the axial direction. A substrate (10) bears detecting and exciting means co-operating with the resonator. Said detecting and exciting means co-operate with an axial component of a vibration of the resonator.
Le capteur gyroscopique comprend un résonateur (14) en forme de cloche ou de calotte de révolution, fixé suivant son axe et présentant un bord circulaire situé dans un plan perpendiculaire à l'axe, à distance du point de fixation du résonateur dans le sens axial. Un substrat (10) porte des moyens de détection et d'excitation coopérant avec le résonateur. Ces moyens de détection et d'excitation coopèrent avec une composante axiale d'une vibration du résonateur.
