Product Description
Overview
The Honeywell LG/EG flame monitoring system detects ultraviolet (UV) radiation emitted by hydrocarbon flames. It provides reliable flame/no-flame status signals and has been a proven solution for General Electric (GE) gas turbines for over 35 years.
This system is equipped with a Geiger-Mueller-type sensor phototube, capable of detecting UV radiation in the 180–260 nm range. It is solar-blind and resistant to black-body radiation interference.
