Compact flame detector KLC 21

The KLC 21 broadband flame detector is a compact flame detector specially designed for blue-burning combustion systems in forced-air burner applications in the domestic sector.

  • Suitable for increased temperature range (-20°C to +75°C)
  • Compact design
  • Evaluates the flicker frequency under processor control
  • Interfering sources of extraneous light are faded out
  • Signal can be evaluated on PC via optical interface
  • Can be connected to all automatic burner control units with LDR or ionisation input

The KLC 21 broadband flame detector is a compact flame detector specially designed for blue-burning combustion systems in forced-air burner applications in the domestic sector. The patented evaluation of the signal takes place via the flicker frequency of the radiation of the upcoming flame. The device can be operated in an extended temperature range from -20°C to +75°C. A processor enables the evaluation and conversion of the flame signal to a digital signal in the value required for the flame signal amplifier of the corresponding automatic burner control system. Adjustments are not required during commissioning or maintenance.

The KLC 21 only evaluates the flickering of the flame to be monitored. A device version with interference frequency suppression is optionally available.

Uniform light beams and any constant frequencies do not lead to a permanent flame detection. Disturbing sources of extraneous light, e.g. from fluorescent tubes or low-frequency background radiation from glowing brickwork, are suppressed. Unintentional influences on the flame detection can thus be avoided.
Via the LED display as an optical interface, it is possible to read out various relevant operating parameters (e.g. monitoring of the flame signal, serial number).

Show what is happening

For the visualisation of the flame signals of the Flamonitec flame detectors we offer the suitable readout units. An excellent tool for any development department.

Perfect switching

The relay module flame detector converts the output signal of the flame detectors of the KLC series into a potential-free switching output.

Always the right connection

For the optimum connection of flame detectors to control boxes, we also offer customer-specific solutions in addition to our standard range.

Permanently mounted

Various fastening devices provide a tight fit on burner parts.

Looking around the corner

With the optionally available angle adapter, the radial alignment of the KLC 20 or KLC 21 to the flame axis is carried out by means of an optimally shaped mirror surface.
