GE RS-FS-9001

Product Overview

The GE RS-FS-9001 is a high-performance ultraviolet (UV) flame sensor from the Reuter-Stokes Flame Tracker™ series, engineered for industrial high-risk environments requiring reliable flame presence detection. It uses a silicon carbide (SiC) photodiode to capture long-wavelength UV radiation emitted by flames, which penetrates fuel mist, steam, and water vapor better than traditional UV sensors. The two-wire design with 4–20 mA output enables seamless integration with safety controllers, DCS, or PLC systems for rapid alarm triggering and safety shutdowns. It operates reliably in extreme temperatures (with optional water cooling), high pressure, and heavy vibration, making it ideal for combustion systems where false alarms or missed detection could lead to catastrophic incidents. The sensor replaces legacy models like 362A1052P001 and meets global safety certifications for hazardous area use.

Function Features

  • SiC Photodiode Technology: Detects long-wavelength UV from flames, penetrating fuel mist/steam that blocks traditional Geiger-Müller tube sensors.
  • Fast Response: <25 ms detection time ensures rapid safety system activation to prevent fire escalation.
  • Two-Wire 4–20 mA Output: Simplifies wiring and integration with standard industrial control systems; no additional power lines needed.
  • Extreme Environment Operation: Withstands -40°C to 150°C ambient (235°C with water cooling) and 400 psig pressure; resists heavy vibration.
  • High Interference Immunity: Sapphire window and signal processing filter out sunlight, arc welding, and electrical noise; false alarm rate <0.1 per year.
  • Low Power Consumption: 12–30 VDC input at 100 mA max reduces energy use in remote installations.
  • Hazardous Area Certified: ATEX/IECEx approval for use in Zone 1/2 and Class I, Div 1/2 hazardous locations.
  • Robust Construction: Stainless steel housing and IP66/IP68 rating protect against dust, water, and chemical corrosion.
  • Easy Replacement: Drop-in replacement for legacy 362A1052P001 sensors with no system reconfiguration.
  • Diagnostic Capability: 4–20 mA output includes fault states (e.g., open circuit, low power) for predictive maintenance.

Application Scenarios

  • Gas Turbines: Monitors combustion chambers in power generation turbines; detects flame loss during startup/shutdown to prevent fuel buildup.
  • Industrial Boilers: Ensures continuous flame presence in steam/hot water boilers; triggers shutdown if flame is lost to avoid explosions.
  • Petrochemical Refineries: Monitors heaters, furnaces, and flare stacks in hazardous areas; complies with ATEX/IECEx safety standards.
  • Power Plants: Used in coal, gas, and biomass-fired boilers; integrates with DCS for safety interlocks and emissions control.
  • Chemical Processing: Detects flames in reactors, distillation columns, and incinerators; prevents fire spread in flammable material handling.
  • Aerospace & Marine: Monitors auxiliary power units (APUs) and shipboard boilers; operates in high-vibration, high-temperature environments.
  • Waste Incineration: Ensures proper combustion in waste-to-energy plants; avoids unburned waste release and equipment damage.
  • Metal Processing: Monitors blast furnaces, annealing ovens, and forges; maintains process safety in high-heat metalworking operations.

Compatibility and Integration

  • Controller Compatibility: Works with GE Reuter-Stokes flame amplifiers, safety PLCs (Siemens, Allen-Bradley), and DCS systems via 4–20 mA input.
  • Cable Requirements: Uses RS-E2-0285Pxxx or 362A1053Pxxx cables for signal integrity and noise immunity; lengths up to 300 m supported.
  • Water Cooling System: Optional cooling jacket allows operation up to 235°C; connects to plant cooling water lines with ½” NPT fittings.
  • Mounting Options: Flange mount (ANSI 150 lb) or threaded mount (1” NPT); fits standard combustion system ports.
  • Safety Integration: Interlocks with fuel shutoff valves, vent fans, and fire suppression systems; meets NFPA 85 and API 556 standards.
  • Maintenance Tools: Compatible with GE Flame Tracker™ test kits for periodic functional checks without sensor removal.
