Abstract
L'invention concerne les accéléromètres. Elle se rapporte à un accéléromètre léger et petit comprenant un pendule 26 ayant une petite palette 28 placée entre deux plaques 18 et 20 de condensateurs. La palette articulée sur un axe 30 est rappelée en position convenable par un courant de rappel. circulant dans une bobine 36. Le circuit électronique porté par la plaquette 42 permet la détection de différences de capacités de l'ordre de quelques millièmes de picofarad. Application à la réalisation d'accéléromètres petits et légers.The invention relates to accelerometers. It relates to a light and small accelerometer comprising a pendulum 26 having a small vane 28 placed between two plates 18 and 20 of capacitors. The pallet articulated on an axis 30 is returned to the appropriate position by a return current. circulating in a coil 36. The electronic circuit carried by the plate 42 allows the detection of differences in capacitance of the order of a few thousandths of a picofarad. Application to the production of small and light accelerometers.
