Abstract

L'invention concerne un dispositif destiné à être utilisé dans des instruments du type à transducteur tels que des accéléromètres. Ce dispositif comporte un élément mobile portant un capteur et fixé à un élément de support au moyen d'organes flexibles. L'élément de support est lui-même monté en porte à faux entre deux éléments fixes. Ainsi, les erreurs systématiques de l'instrument peuvent être réduites par la mise en alignement des bords des surfaces des éléments fixes portant contre l'élément de support, avec le centre géométrique du capteur, afin que l'axe de rotation du porte-a-faux passe par ce centre géométrique. Domaine d'application : accéléromètres pour instruments sismiques, etc.
