Fireye 95DSS3-1CEXSS
Model: 95DSS3-1CEXSS
Product Name: InSight II Integrated UV/IR Flame Scanner, Stainless Explosion-Protected Version
Product Introduction: This scanner combines ultraviolet and infrared flame detection, signal processing, flame relay logic and diagnostics in one stainless enclosure. It is intended for boilers, gas turbines and marine burners where explosion protection, corrosion resistance and high false-signal rejection are required.
Detailed content
Technical Specifications:
- Detection: Integrated UV and IR sensors
- Housing Material: 316 stainless steel with zinc primer, gray epoxy midcoat and polyurethane topcoat
- Weight: 21.3 lb / 9.66 kg scanner; mounting flange 1.86 lb / 0.84 kg
- Supply Voltage: 24 V DC, +10%/-15%
- Operating Current: 0.35 A
- Output Relays: Two independent flame relays, one fault relay; UV/IR/dual trigger configurable
- Analog Output: Two 4-20 mA channels for flame intensity
- Response Time: Output rise time 20 ms or less
- Protection Rating: IP66
- Explosion Protection: Ex d IIC T6/T5/T4 and Ex tb IIIC T85/T100/T135°C per marine/scanner documentation
- Operating Temperature: -40°C to +65°C
- Humidity: 0-95% RH, non-condensing
- Display: Alphanumeric VFD with keypad; Auto-config and PC Explorer support
Functional Features:
- Dual-Spectrum Logic: UV recognizes spark/flame radiation; IR confirms thermal radiation and rejects single-band false triggers
- Programmable Profiles: Multiple fuel/load configurations
- Modulation Frequencies: Adjustable flame discrimination frequencies
- Cooling/Purge Air: Keeps lens clean and lowers housing temperature
Application Scenarios:
- Marine Boilers: Ship power plants and auxiliary steam generators
- Industrial Burners: Gas, oil and dual-fuel combustion systems
- Hazardous Areas: Refinery heaters, offshore modules and chemical furnaces
- Utility and IPP Boilers: Continuous flame surveillance with safety shutdown
Structural Characteristics:
- Flange: 316 stainless threaded mounting flange, ordered separately; 60-2693 series supports 1 in NPT or BSP with 3/8 in cooling-air connection
- Cable Entry: Scanner housing provides 1/2 in and 3/4 in NPT entries; use certified glands
- Cooling Path: Sight pipe or Y-fitting purge air connection
Working Principle: UV and IR detectors convert flame radiation into electrical signals. The processor evaluates intensity, flicker frequency and dual-sensor agreement, then energizes flame relays when a validated flame exists. Loss of flame, sensor fault or self-test failure activates the fault relay.
Installation Requirements:
- Mount with proper flange and sight pipe aiming at the flame front.
- Provide clean, dry instrument air; standard 4 SCFM / 113 L/min, up to 15 SCFM / 425 L/min for high-temperature or dusty conditions
- Use certified explosion-proof glands and blanking plugs for unused entries.
- Bond and ground all stainless parts in hazardous areas.
Usage Precautions:
- Do not install without purge air where high furnace heat or dust is expected.
- Avoid electrostatic discharge when handling painted stainless in low-humidity hazardous areas.
- Do not block cooling air path.
- Verify Ex certificate, relay logic and 4-20 mA scaling before burner start-up.
