SP-566 | Flame Sensors | Reuter-Stokes | GE | 353B3490G001 | SP-566
The Reuter-Stokes GE Flame Sensors utilize silicon carbide (SiC) photodiodes, exhibiting high sensitivity to long-wave ultraviolet light (UV-C to UV-B), penetrating fuel vapor mist. They feature a response time of ≤25 milliseconds, a wide dynamic range, and strong anti-interference capabilities. Temperatures range from -30°C to 150°C (water/air cooling is required in high-temperature environments); pressure withstand 400 psi; protection rating compliant with ATEX/IECEx explosion-proof certification; suitable for hazardous areas such as Class I Division 1 (North America) and ATEX Zone 1; suitable for low-NOx burners and steam injection applications; supports multi-fuel (natural gas, hydrogen, diesel, etc.), low-NOx burner, and steam injection applications; and complies with NFPA gas turbine flame detection standards.

Technical Parameters and Characteristics
Detection Principle: Employs a silicon carbide (SiC) photodiode, highly sensitive to long-wave ultraviolet light (UV-C to UV-B), capable of penetrating fuel vapor mist, with a response time ≤25 milliseconds, wide dynamic range, and strong anti-interference capability. Suitable for low-NOx burners and steam injection scenarios.
Output Signal: 4-20mA industrial standard analog signal, compatible with various control systems; supports dual digital/analog output.

Explosion-proof Rating: CENEL EC EExdⅡ BT5, suitable for hazardous areas (e.g., Zone 1/Zone 2).
Sensitivity and Range: 4 adjustable ranges (15m/30m/45m/60m), response time ≤2 seconds, viewing angle 90° horizontally/vertically.
Electrical Parameters: Power supply 18~32V DC, normal power consumption 200mA, 150mA under alarm; signal output 4~20mA DC, relay contacts support alarm (2A/30V DC or 250V AC) and fault signals.
Environmental Adaptability:
Operating Temperature: -30°C to 150°C (high-temperature scenarios require water/air cooling); withstand pressure 400psi; protection rating conforms to ATEX/IECEx explosion-proof certification, suitable for Class I Division 1 (North America), ATEX Zone 1 and other hazardous areas. Mechanical Design: 316 stainless steel housing, MIL-C-38999 military-grade connector, quick-disconnect design (reducing replacement time from hours to minutes), resistant to vibration and contamination (e.g., scale detection).
Application Scenarios:
Core Areas: Gas turbine combustion chamber flame monitoring (e.g., heavy industry, power generation, petrochemicals, oil and gas tank farms), ensuring safe start-up, operation, and shutdown.
Extended Applications: Tunnels, ships, aircraft engines, industrial boilers, and other smokeless liquid/gas fire, open flame, and deflagration environments.
Special Advantages: Compatible with hydrogen fuel and mixed fuels; supports low-NOx burners and steam injection applications; extends equipment life through water washing operation.
Compatibility: Supports multiple fuels (natural gas, hydrogen, diesel, etc.), low-NOx burners, and steam injection applications; complies with NFPA gas turbine flame detection standards.
Installation
and Maintenance
Installation Specifications: Grounding and lightning protection are required (grounding resistance ≤ 5Ω). Avoid tangling of signal and power cables; cables must be supported every 3 feet, and the temperature at the cooling end must not exceed 150°C; customized conversion kits are available for compatibility with older system interfaces.
Maintenance Advantages: Quick-change design (connector disconnection within ≤ minutes); sensor cooling system reduces thermal impact; supports customized conversion kits for compatibility with older system upgrades.
