The double tuning fork force transducer consists of two identical parallel prongs (2A, 2B) attached at their ends to two coupling elements (4, 5). The prongs are such that they vibrate flexurally in phase opposition in response to imposed vibrational stresses, with a natural frequency representative of the magnitude of a force F applied longitudinally to the coupling elements. The transducer is layered and consists of two identical elastic strips (10, 11) held apart at their ends (3A, 3B, 3'A, 3'B) by two spacers (8, 9) of the same thickness. The spacers and the ends are firmly gripped in the coupling elements. …<IMAGE>… |
