Distributed Optical Fiber Vibration Sensing System 50km Submarine Cable Damage Monitoring

Distributed Optical Fiber Vibration Monitoring System

DVS Description

Optical Fiber Vibration Sensing System is based on the optical fiber RAYLEIGH scattering principle. It uses the SMF to be the slightly vibration sensing part and also cooperate with the optical fiber vibration main detection controller, the system can real time detect the vibration signal of the optical fiber.

Through the monitor software analysis, the accurate positioning have been made by the vibration source, the type of the vibration signal can be divided, then the system will emit the alarm signal.

Distributed optical fiber vibration sensing system can be used to the anti-damage detection of long distance pipelines, such as oil and gas pipeline, liquid pipeline, pipe gallery, national defense border surveillance and invasion control, coal mine fire collapse rescue workers location, high-speed railway damage and personnel.

The company takes the science and technology as the guide, with strict management and strong research and development team.

    High Strain Dynamic Pile Tester (Also named PDA by PDI company. )  ;  Low Dynamic Pile Tester (PIT or PET for short); Untrasoic Crosshole Pile Tester for 2, 3 ,4 channels.; Drillhole Monitor  (Also named Koden from Japan company. )

High Strain Dynamic Pile Tester projects at field. If clients need, we also can do the testing compare with PDA from PDI company. We already have done testing at different countries. We got very good feedback from our professional pile testing clients and relative company. 

Low Strain Dynamic Pile Tester at field with our software;  Static Load Pile testing at field with our software. 

Drill hole monitor testing at field with 100meter depth, with automatic stop function to save untrosonic sensor drop in wells making lost for inspection company.  We also can supply drillhole monitor with 150m depth.
