Item specifics

Product name: VG941-3AS

Product Description

The sensor is a modification of the VG941-3A which
produced since 1995. It comprises sensing
optical assembly and processing electronics. Main
optical sensing assembly is fabricated using
Fizoptika exceptional “in line spliceless technology”
from specially developed fiber. To reduce size of
the VG941-3A major optical componets and electronics module were redesigned. Design goal
has been achieved to create smallest ever fiber optic gyro with the fastest start-up.
VG941-3AS is produced only in a version with.sensing axis perpendicular to the sensor’s
VG941-3AS is the sensor of absolute rotation. Output of the sensor is defined as voltage
between contacts “+Output” and “-Output” (Balanced) The output is proportional to the
angular rate.
