Functional description

For flame radiation analysis the compact flame controller For flame radiation analysis the compact flame controller
is using the integral method in the respective spectral the integral method in the respective spectral
range.
After pre-amplification, the undesirable unmodulated light
portion is removed from the output signal of the wear ortion is removed from the output signal of the wear-free
detector. The subsequent sensitivity setting permist an at- detector. The subsequent sensitivity setting permist an a

The downstream bandpass ensures that only the typical The downstream bandpass ensures that only the typical
flame radiation modulation of the primary combustion
zone is evaluated. This allows extraneous light signals zone is evaluated. This allows extraneous light signals
from neighbouring burners to be distinguished from the from neighbouring burners to be distinguished from the
monitored flame.
Further function groups include i.a. the signal processing Further function groups include i.a. the signal processing
