Product Short Description
Product Overview
EG1033AC is a Honeywell-manufactured UV Flame Amplifier Module designed for integration with GE (General Electric) turbine control systems, particularly Speedtronic Mark IV/Mark V series. It is a core component of the LG/EG flame monitoring system, which has delivered proven performance on GE and GE-licensed gas turbines for over 35 years. The module works with Geiger Mueller-type UV sensor phototubes to detect UV radiation in the 180-260nm spectral range emitted by hydrocarbon flames, generating a clear flame or no-flame output signal. It features a fast response time, solar-blind operation, and tolerance to black body radiation, ensuring accurate flame detection while ignoring ambient light interference. The module comes with an SPDT relay output for direct interface with turbine safety circuits, and it supports multiple power supply options for flexible system integration. It uses industrial-grade components to ensure reliable operation in harsh industrial environments, with a two-year shelf life and 10,000-hour MTBF, backed by over one billion cumulative operating hours in the field. It serves as a critical safety component that enables turbine control systems to monitor flame presence, trigger alarms, and initiate shutdown protocols to prevent catastrophic failures.
