GN Electronics's flame sensing system consists of ultraviolet self-check and infrared/frequency-based flame detectors.

Flame monitoring system from GN Electronics Inc.consists of ultraviolet self-check and infrared/frequency-based flame detectors. The ultraviolet self-check uses a UV detector tube checked by means of a magnetic shutter while the flame detector uses a photovoltaic cell to sense the infrared light spectrum. Equipped with a fail-safe flame trip circuit and adjustable trip level, Quanta-Flame interprets the flame signal information.
