Hydrogen Flame Detector – D-LE 701

DURAG GROUP

Self-monitoring and fail-safe flame sensor with fibre-optic connection
Monitoring of gas, oil, and coal flames
Connection to D-UG 120, D-UG 660 control unit, and D-GF 150 (-MB) burner control
Spectral range from UV to IR
Uniform output signal for mutual interchangeability

The D-LE 701 and D-LE 703 Flame Sensors are advanced flame monitoring systems designed for industrial applications. These sensors utilize a fibre optic system to transfer flame radiation from the combustion area to the sensor, which generates a signal proportional to the flame intensity. They are self-monitoring and fail-safe, ensuring reliable operation in conjunction with control units or burner controls. The sensors are compatible with a wide range of fuels, including gas, oil, and coal, and can be adjusted for different combustion technologies such as exhaust gas recirculation. They are suitable for challenging installation conditions and are certified with DVGW, EAC, and SIL3. These sensors are ideal for use in power stations, chemical industry, refineries, cement plants, waste incinerators, steam generators, and heating plants. The sensors are available in flexible or rigid fibre optic systems, with options for different protection ratings and operational modes.

Use Cases

Burners with difficult installation conditions for conventional flame sensors or on those where ambient temperature near the sighting tube is very high
Power stations
Chemical industry
Refineries
Cement plants
Waste incinerators
Steam generators
Heating plants
Hydrogen burner monitoring (100% H2 or H2-mix fuels)
