D-LE 603 Flame sensor
D-LE 603 Flame sensor
D-LE 603 Flame sensor (flame scanner) for monitoring gas, oil and coal flames, primarily in multi-burner view applications.
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. The D-LE 603 flame sensor is available with different photo elements for maximum selectivity when using various fuels.
Features:
- Self-monitoring and fail-safe in conjunction with a control unit / burner control
- Flame sensors for every spectral range from UV to IR
- Connection to the D-UG 120 control unit, D-UG 660 control unit as well as to the D-GF 150 (-MB) burner control
- Uniform output signal thus mutually interchangeable
- Adjustable to different combustion technologies such as exhaust gas recirculation
- Compliance to general safety regulations
- ATEX approved (D-LE 603 …/94 Ex for zone 1 and D-LE 603 …/97Ex for zone 2)
Applications:
- Power stations
- Chemical industry
- Refineries
- Cement plants
- Waste incinerators
