原装SIEMENS LFE10火焰检测器，燃烧器配件

flame safeguards for burners with intermittent operation. for
safety reasons - self-test of flame supervision circuit, etc. - at least one
controlled

shutdown is required every 24 hours. the lfe10 is suited for the
supervision of gas flames and luminous or blue-burning oil flames in connection
with uv detectors qra... or a flame rectification probe.

flame safeguards are used primarily in conjunction with the lec1
burner control on the following applications:

• dual-supervision of burners: supervision of the main flame or of
  the pilot and main flame by two identical or different types of flame detectors

• supervision of forced draught oil / gas burners: supervision of
  the flame with different types of detectors, depending on the operating mode

• multi-flame supervision: plants with several burners whose flames
  must be supervised individually by one or several detectors, whose startup and
  supervision, however, should or must be carried out centrally and simultaneously
  by only one burner control

• the flame safeguards can also be used in connection with other
  types of burner controls provided the given combination and selected circuitry
  do not impair the burner control’s safety functions

• the flame safeguards are also used as flame indication units in
  combustion plant with manual startup
