Abstract
The shock resistance of an accelerometer for the measurement of an axial acceleration, having a sensing part consisting of an electromechanical beam, a spacer and a beam carrier can significantly be improved by making the two sections of the oscillating beam of unequal lengths and by providing the beam with a length between 8 mm and 11 mm and a width between 2.5 mm and 6.5 mm at a thickness of 0.6 mm. That way an optimum relationship between measuring sensitivity and shock resistance of the accelerometer will be reached.
