Description
The BEI GyroChipTM Model QRS11 is a "MEMS " technology, solid-state "gyro
on a chip." This DC input/high-level DC output device is fully self contained,
extremely small and lightweight. No external support electronics are required.
Since the inertial sensing element is comprised of just one micromachined
piece of crystalline quartz (no moving parts), it has a virtually "unlimited" life.
The Model QRS11 is a mature product in high volume production. It is fully
qualified and used on numerous advanced aircraft, missile, and space systems.

Operation
The BEI GyroChipTM Model QRS11 utilizes a one piece, micromachined, vibrat-
ing quartz tuning fork sensing element. Applying the Coriolis effect, a rotational
motion about the sensor's input axis produces a DC voltage output proportional
to the rate of rotation. Use of piezoelectric quartz material simplifies the active
element resulting in exceptional stability over temperature and product life.

NOTES:
1. QRS11 IS SUPPLIED WITH TWO MOUNTING RINGS,
MOUNTING SCREWS & MATING TEST CONNECTOR.
2. ANGULAR RATE APPLIED AS SHOWN WILL PRO-
DUCE A POSITIVE OUTPUT (NOT MARKED ON UNIT).
3. UNIT OF MEASURE IS IN INCHES/[MM].
4. A DC VOLTAGE INPUT (1.0 Vdc MAX.) APPLIED TO
THE SELF-TEST WILL RESULT IN A CORRESPOND-
ING PROPORTIONAL DC OUTPUT VOLTAGE.
5. TTL COMPATIBLE BIT OUTPUT SIGNAL OF
2.4 Vdc
(REFERENCED TO POWER GROUND) INDICATING A
