SENSORS
PIEZOELECTRIC VIBRATING GYROSCOPE
ENC SERIES
This angular velocity sensor employs the
principle that a Coriolis force results if an
angular velocity is applied to a vibrating
object. Murata’s unique ceramic bimorph
vibrating unit is used as the sensor element
unit, thereby enabling piezoelectric ceramics
to be used for both excitation and detection.
The use of this unit simplifies equipment
structure and circuit configuration, thus
making it possible to provide outstanding
performance.
This sensor can be used for positional control
and posture control of a moving object
requiring high-precision measurements.
FEATURES
I Ultra small and ultra lightweight
I Quick response
I Low driving voltage, low current
consumption
I Reliable feature achieved by a built in
AGC circuit
APPLICATIONS
I Detecting hand movement involved in
video and still camera
I Detecting vibrations in various vibration
free table and isolators
I Detecting the own movement
