Abstract
A transducer element for measuring angular and linear accelerations including a pair of electromechanically reacting oscillating beams held symmetrical to a main axis y on a base plate by fixing elements. The electrical output signals proportional to the flexure of the beams under rotation about the y axis are provided to a signal processing circuit, which is designed so that with similar or dissimilar polarity of the oscillating beams a summing amplifier determines the linear acceleration along the z axis and a differential amplifier the angular acceleration about the y axis. The oscillating beams may be piezoelectric bending elements, or bending elements coated with piezoresistive semiconductors, or else provided with strain gauges.
