GE RS-FS-9009-03 (Reuter-Stokes Flame Tracker Dry 325) UV Flame Detector

Product Description
RS-FS-9009-03 is a GE Reuter-Stokes (now Baker Hughes) FTD325 dry-type ultraviolet flame sensor, OEM part 124T5712P0001. It adopts silicon carbide (SiC) photodiode UV detection technology, split hot-end and cold-end design connected by mineral insulated cable. The hot end mounts directly on gas turbine combustion can, no water cooling required, detecting flame UV radiation while rejecting false signals from hot furnace walls. It outputs standard 4–20mA flame intensity signal to burner management / turbine control system for flame safety supervision.

Key Features

• SiC UV photodiode sensor, immune to infrared thermal background interference, suitable for low-NOx combustors
• Split construction: Hot end -51℃ ~ +325℃; Cold end -51℃ ~ +150℃, no cooling water needed
• Response time less than 0.175s, fast flame loss detection for turbine trip protection
• 4–20mA analog output proportional to flame intensity, easy connection to BMS / turbine control system
• ATEX, IECEx and DNV hazardous area certification, Zone 2 rated
• Integrated mineral insulated high-temperature cable assembly, robust for vibration and thermal cycling
• Single sealed assembly, cannot be disassembled on site; damage will invalidate safety certification
• Originally GE Reuter-Stokes brand, now belongs to Baker Hughes; still available as spare parts for gas turbine retrofit

Application Scenarios

• Heavy-duty gas turbine combustion chamber flame monitoring (GE gas turbine units)
• Combined cycle power plant, cogeneration plant burner safety supervision
• Refinery, petrochemical process heaters and high-temperature furnaces
• Power plant burner management system (BMS) flame safety loops
• Legacy GE turbine flame detection spare replacement and upgrade projects

FAQ

Q: What is the difference between RS-FS-9009-03 and RS-FS-9010-03?
A: RS-FS-9009-03 is standard gain version; RS-FS-9010-03 is high-gain variant for weak flame conditions.

Q: Does this flame sensor need cooling water?
A: No, it is Dry 325 series, air-cooled without water cooling system.

Q: What signal does RS-FS-9009-03 output?
A: 4-20mA analog signal representing flame intensity, sent to BMS or turbine controller.
