Introduction

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.

1. Features

- Ultra small and ultra lightweight

- Quick response

- Low driving voltage, low current consumption

- Reliable feature achieved by a built in AGC circuit

2. Applications

- Detecting hand movement involved in video and still camera

- Detecting vibrations in various vibration free table and isolators

- Detecting the own movement
