Description
The BEI GyroChipTM Model AQRS is a compact, rugged micromachined
vibrating quartz gyroscope, designed specifically for demanding automotive
and commercial applications. It operates from +5 Vdc and features a 3-wire
interface with ratiometric output signal for greater flexibility. Internal
circuitry provides protection for reverse voltage and over voltage conditions,
and an end-to-end Built-in-Test (CBITTM) continuously monitors sensor
performance for safety-critical applications.

Operation
The BEI GyroChipTM Model AQRS utilizes a micromachined double-ended
quartz tuning fork fabricated from monocrystalline piezoelectric quartz.
Applying the Coriolis effect, a rotational motion about the sensor's input axis
produces a DC voltage proportional to the rate of rotation. Use of piezoelectric
quartz material simplifies the active element, resulting in exceptional stability
over temperature and product life.
