70Y digital instrumentation
Application of Principle: This product uses Sagnac ( Sagnac ) interference principle , with a laser as a light source , the optical fiber constituting the ring - type optical path , and detection by the pros -clockwise along the optical fiber transmission of two beams of light with the optical fiber ring is rotated to produce the two channels of laser beam phase difference between the calculated rotational angular velocity of the optical gyro .
Product Features: The product features faster startup speed , dynamic range , long life and high reliability . Apply to the higher requirements of high-precision measuring system and servo system reliability .
