Description

The B E I GyroChip I I 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 P OWER -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 • DC Input/High-Level DC Output

• Compact, Lightweight Design • Internal Power Regulation

• Wide Temperature Range • P OWE R SAVE Mode

• High Reliability (+12 Vdc Version)

Operation

The B E I GyroChip™ I I 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.
