Abstract
Accéléromètre linéaire équipé d'un système de rééquilibrage perfectionné pour remettre en place la masse sensible à l'accélération. L'accéléromètre comprend : un aimant produisant deux champs magnétiques dans des zones annulaires centrées sur un axe d'entrée de l'accéléromètre; une bobine ou masse sur laquelle sont enroulés deux bobinages en sens opposés, connectés en série et placés dans lesdites zones ; un système de suspension de la bobine; des moyens de détection du déplacement de la bobine à partir d'une position prédéterminée; et un servosystème, relié auxdits moyens de détection, qui fournit un courant de rééquilibrage aux bobinages pour maintenir la bobine dans ladite position prédéterminée. Application aux accéléromètres linéaires.
