<p>A resonant sensor (210) comprises a support structure (202) comprising two support points (204,206); a laminar resonator (214) suspended between the two support points (204,206) of the support structure (202) and comprising a plurality of substantially parallel flexural members (230) which are responsive to relative movement of the support points (204,206); means (236,238) for exciting the resonator (214) into a balanced mode of oscillation and means (232,234) for sensing motion of the resonator (214). <??>The means (232,234) for sensing motion of the resonator (214) is or are spaced from, and linked to, the flexible area (230) of the resonator by means of levers (240,242). <??>The support points (204,206) are preferably adapted to move relative to each other in response to a difference in pressure, force or acceleration. <IMAGE></p> |
