Description
Manufacturer: Reuter-Stokes (GE)
Part Number: RS-FS-9001, 362A1052P404
Product Type: SiC Ultraviolet Flame Detector Sensor for Gas Turbine BMS
Product Overview
The RS-FS-9001 (362A1052P404) is a silicon carbide UV flame sensor manufactured by Reuter-Stokes, a GE brand. It is designed for gas turbine, boiler and burner management systems (BMS). It detects ultraviolet radiation emitted by combustion flames and converts flame intensity into a 4–20mA analog signal for turbine control systems including Mark VI, Mark VIe. It provides fast flame loss trip signal to prevent dangerous unburned fuel accumulation inside combustion chambers.

Key Features
- SiC UV sensor technology, highly resistant to fuel vapor, smoke and hot background radiation interference.
- Fast flame detection response, critical for gas turbine safety shutdown logic.
- 2-wire 4-20mA loop output, easy integration with turbine BMS and DCS racks.
- Rugged stainless steel body, suitable for high vibration, high temperature turbine enclosure environments.
- Continuous real-time flame intensity monitoring, not only simple flame present / no-flame contact signal.
- Direct drop-in replacement for legacy Reuter-Stokes flame sensor part numbers.
Application Scenarios
- Gas turbine power generation units (Mark VIe control system)
- Large industrial boiler burner management safety system
- Refinery process heaters and combustion safety monitoring
- Combined cycle power plant combustion chamber flame supervision
Installation & Maintenance Notes
- Mount the sensor in correct sight tube, ensure optical line of sight to flame; avoid soot contamination on the viewing window.
- Use shielded twisted pair cable for 4-20mA signal wiring, single-point shield grounding.
- Do not exceed specified DC supply voltage range to prevent sensor damage.
- Clean the viewing lens during scheduled outages; soot buildup reduces flame detection sensitivity.
- Perform flame signal check during commissioning, verify 4–20mA reading matches flame status.
- Confirm part number compatibility before replacement with existing turbine BMS.
