Abstract: La invencion se relaciona con un acelerometro electromagnético que comrpende una parte sensible de silicio con una masa movil (2) unida a un marco (3) periférico por medio de brazos (80, 81) de suspension. La parte sensible de silicio de solidaria de un motor (1) de rigidez denominada negativa que comprende un recinto (12) polar tipo unido al marco periférico, un imán (5), una bobina (6) y una parte polar (4) movil insertada en el recinto (12); esa parte polar es solidaria de la masa movil (2). El acelerometro es util en geofonos.

Abstract: An accelerometer based on single-crystal silicon and including a movable weight (1) connected to a stationary frame (3) via suspension arms (21, 22). The resulting sensor is formed in a stack of two silicon plates (6, 7) provided with abutment (43, 44, 47, 48) and counter-abutment (41, 42, 45, 46) functions for limiting the magnitude of the movements of the movable weight (1).

Date Jun. 19, 1997An accelerometer based on monocrystalline silicon. A moving mass is connected to a fixed frame by suspension arms. The sensor is produced in the stack of two silicon wafers in which stop and counter-stop functions are produced so as to limit the amplitude of the movements of the moving mass.
