D-LE 701, D-LL703 Flame sensor

D-LE 701, D-LL703 Flame sensor

D-LE 701 fibre optic system may be integrated directly into the hot area of the burner. It transfers the radiation from the flame over a fibre optic bundle to the flame sensor installed outside the burner. It is available in different lengths. The photo element in the flame sensor generates a signal which is proportional to the flame radiation intensity. The output signal of the flame sensor is used as an input signal to a control unit or a burner control.

Features:

• Self-monitoring and fail-safe flame sensor with a fibre-optic connection in conjunction with a control unit / burner control
• Monitoring of gas, oil and coal flames
• Connection to the D-UG 120, D-UG 660 control unit and the D-GF 150 (-MB) burner control
• Spectral range from UV to IR
• Uniform output signal thus mutually interchangeable
• Adjustable to different combustion technologies such as exhaust gas recirculation

Applications:

• 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
