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.
