The accelerometer has a seismic mass (5) attached to a base (1) via a bolt (6) passing through the base (1) and a piezoelectric transducer (2,3) between the base (1) and the mass (5). The transducer (2,3) responds to the forces exerted on the latter transverse to the axis of the bolt (6) and has at least one pair of counter-clock transducer electrodes (3a,3b) providing additive output signals. Pref. 4 pairs of transducer electrodes each occupy one quarter of the surface of the piezoelectric element (2), with the opposing electrode pairs connected in anti-parallel. |
