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

5002 Series consists of ultra-violet self-check and infrared/frequency-based flame detectors. The UV scanner contains a UV detector tube that is checked by means of an optical interrupter. The infrared/frequency-based detector uses a photovoltaic cell that senses light in the infrared spectrum. The flame sensors are equipped with an internal microcomputer that automatically adjusts sensitivity. From GN Electronics Inc., the system can be interfaced with a PLC or computer.
