<p>The transducer has a piezoelectric tuning fork with a detection leg (24) having two grooves (33, 34; 35, 36) longitudinally etched onto each of top and bottom faces, and mechanical uncoupling units. Detection units has detection electrodes (27a, 28a, 27b, 28b) arranged respectively on lateral flanks of the grooves (33, 34; 35, 36), so that electrical paths between the respective electrodes are rectilinear via the leg. The mechanical uncoupling units are provided between a part and excitation and detection legs (23, 24), where the part secures a base of the tuning fork to a gyrometer.</p> |
