Flame Sensing System
The 5002 series system consists of ultra-violet self-check and infrared/frequency based flame detectors. The ultra-violet scanner contains a high quality UV detector tube, which is checked by means of a unique optical interrupter capable of 100 million operations (about 30 years). The infrared/frequency based uses a photovoltaic cell, which senses the infrared light spectrum. The flame sensors are equipped with an internal microprocessor, which automatically adjusts sensitivity and allows for a variety of signal outputs directly from the scanner.
