Video Enhanced Flame Detection (VEFD™)
The FlameSpec™ Blade detector combines the superior detection, stability, and reliability of the market-leading FlameSpec™ IR3-HD flame detector with the latest AI advances in video flame imaging to deliver a new standard in flame detection.
The combination delivers extremely fast detection of visible hydrocarbon fires, with near-total immunity to false alarms, including to those caused by flare reflections.
Considering the costs for a shutdown due to a false alarm on an FPSO might typically range from $500,000 to $5 million, it’s clear that alarms due to reflected flares are financially damaging.
Description
Key Benefits
- Highest immunity to false alarms and high immunity to reflected flares – FM certified.
- Video Enhanced Flame Detection (VEFD™). Visible hydrocarbon flame detection using three clearly separated IR wavelengths (4.0–5.0 μm), combined with near-IR imaging for superior performance.
- Each sensor has the same field of view to further improve false alarm immunity.
- HD, or composite, video output with automatic HD video recording of fire events.
- Fast flame detection, typically less than 5 seconds.
- Detects up to 147 ft (45 m) for a 1 ft2 (0.1 m2) n-heptane fire.
- 5 selectable sensitivity levels.
- 3- and 4- wire, 0—20 mA sink / source, Alarm, Auxilary, and Fault Relays.
- RS485 port using Modbus RTU.
- Event logger: Alarms, faults & videos are logged to non-volatile memory for post-event analysis and investigation.
- Built-in-Test (BIT) – Automatic and manual self-test of window cleanliness and overall detector operation, plus HART® 7, for configuration and maintenance.
- Dirty optics warning for preventive maintenance needs.
- Window heater to avoid condensation and icing.
- Stainless steel tilt mount with horizontal and vertical adjustment.
