ROTATION RATE TRANSDUCER Russian patent published in 2011 - IPC G01C19/56 G01P9/04 

FIELD: physics.

SUBSTANCE: rotation rate transducer contains a substrate and two structures (100, 200, 300, 400, 500, 600) designed so that to enable relocation relative to the substrate on the working plane (x-y). The two movable structures (100, 200, 300, 400, 500, 600) are connected so that to form a unified structure having a first oscillation mode with deviation in the movable structures antiphase in the first direction (x) on the working plane (x-y) as the excitation mode and a second oscillation mode as the detection mode that is to be excited by Coriolis acceleration during the first oscillation mode excitation and during rotation relative the rotation rate transducer sensitive axis (z) that is positioned at a right angle to the working plane (x-y) of the rotation rate transducer. The interfaced structure is designed so that the excitation mode that can be excited by linear accelerations of the rotation rate transducer in a direction parallel to the second axis is non-existent in it under ideal preliminary conditions.

EFFECT: invention enables avoidance of measurement errors conditioned by individual movable structures in case of rotation rate transducers during linear accelerations occurrence.
