<p>The transducer has a piezoelectric tuning fork with a detection leg (24) having a cross-shaped section. The section has top lateral faces (33, 34) comprising opposite vibration detection electrodes (27a, 28a), and bottom lateral faces (37, 38) comprising opposite vibration detection electrodes (27b, 28b), such that electrical field between the electrodes are rectilinear through the leg. Protruding parts (41, 42) separate the top and bottom faces.</p> |
