Abstract
A resonant sensor comprises a support structure comprising two support points; a laminar resonator suspended between said two support points of said support structure and comprising a plurality of substantially parallel flexural members which are responsive to relative movement of said support points; means for exciting said resonator into a balanced mode of oscillation and means for sensing motion of said resonator. Said means for sensing motion of said resonator is or are spaced from, and linked to, said flexible area of said resonator by means of levers. Said support points are preferably adapted to move relative to each other in response to a difference in pressure, force or acceleration.
