Description
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).
