DEF

The part of the flame detection system which increases the flame signal to a magnitude sufficient to pull in the flame relay in the flame safeguard control. The amplifier may be a permanent part of the flame safeguard control, or it may be a replaceable, plug-in unit.

CONT

Hegwein pilot burners are compact, sturdy, and feature a modular design. Models are available with a built-in ignition transformer, or with both flame signal amplifier and ignition transformer.

OBS

Flame signal: the current measured at the meter jack of a flame signal amplifier in a flame safeguard control. The current is produced by the flame detector when it senses a flame.

OBS

Conventional multi-burner scanners have relied on the strength or amplitude of the flame signal to discriminate between burner flame-on and burner flame-off. This is most often done by using the amplitude output of the flame signal after bandpass or highpass filtering.
