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.

Abstract: An accelerometer, consisting of a body having a threaded coaxial nipple for screwably securing the body to a mounting base having a connection for a signal transmission cable. The mounting base can be glued firmly or screwed to a measuring surface, and configured so that accelerometers may be mounted thereto and oriented in several axial directions. It is therefore possible to investigate several axis directions successively using one accelerometer. The object to be measured out can be provided with a large number of single- or multi-axis mounting bases, enabling the entire surface of an object to be measured stepwise in one or more axes, using one or only a few accelerometers. Furthermore the detachable connection between mounting base and accelerometer body facilitates occasional calibration of the accelerometer away from the particular measuring object.
