Title (EN) PIEZOELECTRIC ACCELEROMETER
(FR) ACCELEROMETRE PIEZOELETRIQUE
Abstract:
(EN) A piezoelectric accelerometer comprises a sensitive cylindrical piezoelement (1) subjected to the shearing strain from an inertial element (2) provided, along its maximum sensitivity axis (A), with a through opening (17) for the first current tapping (15) passing from one end-face of the piezoelement (1) to the other one near which the first current tapping (15) is electrically connected to its internal lateral surface, whereas the second current tapping (16) is electrically connectd to the external surface of the cylindrical piezoelement on the side of the first end-face of the cylindrical piezoelement (1), near which is located the outlet point of the current tappings (15, 16), provided with a stiffener (7) embracing the latter.
(FR) Un accéléromètre piézoélectrique comprend un piézoélément (1) cylindrique sensible, soumis à la déformation de cisaillement d'un élément inertiel (2) doté, le long de son axe (A) de sensibilité maximum, d'un orifice (17) de passage destiné à la première prise (15) de courant passant d'une face terminale dudit piézoélément (1) à l'autre près de laquelle la première prise (15) de courant est connectée électriquement à sa surface latérale intérieure, tandis que la seconde prise (16) est connectée électriquement à la surface extérieure du piézoélément cylindrique, sur le côté la première face terminale dudit piézoélément (1) cylindrique, à proximité duquel est situé le point de sortie des prises (15, 16) de courant, doté d'un raidisseur (7) entourant ce dernier.
