Flame Sensor

The flame scanners FFS07 and FFS08 are developed for the different, spectral bands of radiation as well as different types of fuel:

  • Applicable for outdoor area usage
  • FFS07 applicable Ex-Zone II
  • FFS07 Ex applicable Ex-Zone I + Ex-Zone II
  • Available types for UV and IR
  • DIN EN 61508 Part 2 – SIL 3
