Retrofit kit KLC 20

The KLC 20 conversion kit has been specially composed for the simple replacement of an existing flame sensor.

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

Description

The KLC 20 is a compact UV flame detector designed for use in single burner applications and reacts to the flickering frequency of the flame. It is specially designed for blue-burning flames and is therefore ideally suited for switching from conventional fuels to cerosene, HVO, biogas and other e-fuels, as the existing burner control unit does not need to be replaced when using the KLC 20.

The flame detector is equipped with an optical interface that visibly indicates the intensity of the flame signal. The KLC 20 can be connected directly to the ionisation/LDR input of the burner control box. The plug-in solution means that the flame detector can be easily replaced.
