General Description

GYPRO? product line is an established family of Micro-Electro-Mechanical Systems (MEMS) angular rate sensor specifically designed for demanding applications.

The MEMS transducer is manufactured using Tronics proprietary vacuum wafer-level packaging technology based on micro-machined thick single crystal silicon.

The integrated circuit (IC) provides a stable primary anti-phase vibration of the ‘drive’ proof masses, thanks to electrostatic comb drives. When the sensor is subjected to a rotation, the Coriolis force acts on the ‘sense’ proof masses and forces them into a secondary anti-phase movement perpendicular to the direction of drive vibration, which is itself counter-balanced by electrostatic forces. The sense closed loop operates as an electromechanical ΣΔ modulator providing a digital output. This output is finally demodulated using the drive reference signal.

The sensor is factory calibrated and compensated for temperature effects to provide high-accuracy digital output over a broad temperature range.

Raw data output can be also chosen to enable customer-made compensations.
