Abstract
A multicomponent acceleration sensor in which the inertial force of a seismic mass effects a variation in an electromagnetic quantity of a plurality of individual transducers. During acceleration, the seismic mass acts in each individual transducer a magnetoelastic measuring layer, the permeability .mu..sub.r of which influences the inductance of a sensor coil. For each spacial direction in which the acceleration is to be determined, a pair of transducers is mounted on a base member coaxially to, and axially spaced from, each other in such a way that an acceleration of the acceleration sensor perpendicular to the axial direction of the sensor coils of the two individual transducers causes an equidirectional variation in inductances of the sensor coils of the two individual transducers, and a signal representing the acceleration status is obtained in at least one evaluation electronics form the inductances of the sensor coils.
