DFA-M8000 introduces the latest generation of high-speed data acquisition design and wellbore temperature real-time monitoring algorithm based on FPGA and ARM integration with independent property rights, which strengthens the ability of sensing signal exploration and feedback, improves the signal acquisition solution, comprehensively improves the software analysis ability, enriches the application scenarios of equipment, and has faster application feedback. This series of products have intelligent functions of temperature self-calibration, remote terminal control and data transmission.

Technical superiority and highlights

Based on the principle of backward Raman scattering, it is only sensitive to temperature and does not require the design of stress-free special optical cable.

Optical fiber itself is a sensor, which can realize real-time long-distance distributed temperature monitoring.

Optical fiber is a passive sensor, which can be installed in strong electromagnetic radiation, flammable and explosive environments.

Optical fiber is resistant to high temperature and corrosion, small in size and light in weight, and can be used in various harsh environments.

L High spatial and temperature resolution

With real-time online temperature automatic calibration device, it has very high temperature measurement accuracy.

L Available for single or dual port fiber configuration measurement

Real-time high-precision fault point location and detection

1064nm (12km) or 1550nm (20km) wavelength equipment can be selected according to well depth and downhole temperature environment

Multi-channel DFA equipment can be selected according to the actual well volume, which can realize real-time monitoring of multiple wells at the same time.

Scope of application

Fire monitoring and alarm for tunnels, subways and high-rise buildings

L Power line monitoring

Oil and gas well monitoring

Temperature monitoring of power plants, substations and other large equipment

Leakage monitoring of large oil tanks and natural gas tanks
