D-GT 800

Flame sensor

Flame sensor (flame scanner) for the monitoring of gas and oil flames, primarily in gas turbines or in particularly harsh environments.

Overview

  • Optionally available with air/water cooling
  • Deployable with high combustion chamber overpressure
  • High vibrational stability.
  • Conforms to general safety regulations
  • Self-monitoring and fail-safe in conjunction with a control unit/burner control
  • Connection to the D-UG 120, D-UG 660 control unit and the D-GF 150 burner control

Applications

  • Burners with difficult installation conditions for conventional flame sensors or on those whose environmental temperature near the sighting tube is very high
  • Power stations
  • Chemical industry
  • Refineries
  • Waste incinerators
  • Steam generators
  • Heating plants
  • Gas turbines
