Hanvy - Distributed Optical Fiber Vibration / Acoustic Sensing System (DAS/DVS)

The distributed optical fiber vibration sensing system uses an optical fiber as a sensitive element. The sensing optical fiber is both a sensitive unit and an information transmission channel. Through the various disturbances transmitted to the optical fiber (cable) by directly touching the optical fiber (cable) or the optical fiber carrier, the distributed vibration sensor can accurately obtain the vibration signal along the optical cable, and at the same time realize the positioning of the vibration source.It can detect up to 62 miles. Scope of application: petroleum pipelines, oil and gas pipelines, buildings, petroleum storage tanks, subway tunnels, coal belt conveyors, smart pipe corridors, warehouses, bridges, power cables, natural gas stations, borders, PCCP pipelines, high-speed rail tunnels, ancient buildings, geological surveys , Highways, oil production stations, geothermal exploration, thermal energy storage tanks, oil wells, etc.
