The invention concerns a sensor comprising two identical vibrating elements operating at a common working frequency and interconnected by a mechanical decoupling device. The device consists of a frame (DM’) and two connecting bridges (7, 7) each supporting one element. The sensor is characterized in that the frame (DM') consists of a series of solid parts (63, 64, 65, 66) and thinned parts (11, 12, 13, 14, 15, 16) such that the frequency of a structural resonant mode of the frame is equal to the common working frequency and that each connecting bridge (7, 7) is arranged in a vibrating node of the structure at said frequency. Thus, the vibrations of the two vibrating elements are decoupled from each other. |
