Description
The BEI GyroChip II is a compact, rugged, solid-state inertial sensor used to
measure angular rotation rates. It features a monolithic quartz sensing element,
internal power regulation and DC input/high-level DC output operation. Two
versions are available. The +12 Vdc version features a high-level 0 to +5 Vdc
output, integral POWER-SAVE mode, and operation from standard battery
power. The ±15 Vdc version provides a high-level bipolar output of ±5 Vdc,
and is designed for use with conventional double-sided power supplies.

· High Reliability
(+12 Vdc Version)
Operation
The BEI GyroChipTM II utilizes a one piece, micromachined, vibrating quartz
tuning fork sensing element. 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.
