Beschreibung
Zusammenfassung:	The invention relates to an accelerometer device for determining the acceleration of an object to which the accelerometer device is mechanically connected, along 3 axes X, Y and Z of a main orthonormal reference system comprising three axes X, Y and Z. Said object is subjected to a surrounding pressure and comprises a number N of MEMS-type accelerometer sensors, said number N being at least equal to two. Each sensor is defined in an auxiliary reference system comprising 3 orthonormal axes. Said group of accelerometer sensors comprises at least one pair of sensors mounted such that the heads are opposing, the sensors being substantially parallel to each other.
