D-LE 703 flame sensor (flame scanner) for use with
- flexible fibre optic system D-LL 703
- rigid fibre optic system D-LL 704
OVERVIEW
- 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 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 whose environmental temperature near the sighting tube is too high
- Power stations
- Chemical industry
- Refineries
- Cement plants
- Waste incinerators
- Steam generators
- Heating plants
ACCESSORIES
- Digital display for measuring the pulse rate and its extreme values (D-ZS 087-20)
