BEI GYROCHIPTM II Micromachined Angular Rate Sensor Applications * Platform Stabilization * Short Term Navigation * GPS Augmentation * Camera Stabilization * Instrumentation * Robotics * Autonomous Vehicle Control 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. Features * * * * Solid-State Compact, Lightweight Design Wide Temperature Range High Reliability * DC Input/High-Level DC Output * Internal Power Regulation * POWER SAVE Mode (+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.
