The GE RS-FS-9001 (General Electric part number 362A1052P404) is an industrial ultraviolet (UV) / optical flame detector sensor engineered for General Electric Speedtronic (Mark V, Mark VI, Mark VIe) gas turbine control and safety instrumented systems.
Installed around the turbine combustor cans, the RS-FS-9001 continuously monitors the presence or loss of flame during light-off and continuous operation. It transmits high-speed optical flame intensity feedback directly to primary turbine control packs (such as the GE IS220PTURH1B or TRPG/TTUR terminal boards) to trigger rapid fuel gas shutoff if combustion instability or flameout occurs.

Core Features & Operating Capabilities
- High-Speed Flame Detection: Detects the characteristic narrow-band UV radiation generated by hydrocarbon fuel combustion (natural gas, liquid fuel distillate) within milliseconds.
- Insensitive to Background Radiation: Blind to solar radiation, visible light, and hot turbine casing/refractory glow, eliminating false flame indications.
- Explosion-Proof Heavy-Duty Enclosure: Encased in a rugged stainless steel housing designed to withstand extreme thermal cycling, vibration, and hazardous gas atmospheres in gas turbine enclosures.
- Direct Speedtronic Integration: Interfaces directly with GE Mark V, Mark VI, and Mark VIe primary turbine I/O boards (such as TTUR / TRPG / PTUR) without needing external signal converters.
- Combustion Stability Monitoring: Operates in multi-sensor configurations around combustor transition pieces to provide individual burner flame verification and overall system safety tripping.
