Crowcon Fgard IR3
Fast and reliable flame detection for demanding environments. The Fgard IR3 from Crowcon is a multi-spectrum infrared flame detector designed to rapidly and accurately detect hydrocarbon-based fires.
By analyzing three separate IR wavelengths with advanced algorithms, the device offers high sensitivity and minimizes the risk of false alarms — even in challenging industrial conditions.
Key Features:
- Long detection range: Detects a 0.1 m² fire at up to 60 meters in under 5 seconds
- Multi-spectrum IR analysis: Reliable detection from all hydrocarbon sources
- Automatic optical self-test: No need for manual mirror tests
- Heated optics: Prevents fogging, icing, and water build-up on the sensor
- Durable design: Aluminium or stainless steel housing, IP66 / NEMA 4X protection
Technical Specifications:
- Response time: < 5 seconds
- Operating temperature: -76°C to +85°C
- Power supply: 24 VDC (18–32 VDC)
- Outputs: 0–20 mA, HART®, relays (alarm and fault)
- Housing material: Copper-free aluminium or 316 stainless steel
- Certifications: SIL 2, ATEX, IECEx, FM, IP66
Typical Applications:
- Oil & gas facilities (onshore/offshore)
- Petrochemical and chemical industries
- Pharmaceutical and printing industries
- Aircraft hangars, warehouses, power plants
- Tunnels, LNG/LPG stations, recycling plants
