UV & IR Flame Detector FLD-3311-FLP | SIL2 Certified
The UV & IR FLAME DETECTOR FLD-3311-FLP is a high-performance, SIL2-certified flame detector designed to provide fast, accurate, and reliable fire detection in hazardous and industrial environments. This advanced UV IR detector combines ultraviolet and infrared sensing technologies to detect hydrocarbon and non-hydrocarbon flames while effectively rejecting false alarms from sunlight, hot surfaces, welding arcs, and electrical noise. Engineered for mission-critical safety applications, this UV flame detector and IR flame detector offer rapid response time, a wide field of view, and adjustable sensitivity levels to suit different risk zones. The rugged SS-316 stainless steel enclosure with IP66/IP68 protection ensures dependable operation in extreme temperatures, high humidity, and corrosive atmospheres. Built-in self-diagnostics continuously monitor detector health, improving system reliability and plant safety. The SIL2 certified UV IR flame detector supports analog 4-20 mA, relay outputs, and optional RS-485 Modbus RTU and HART communication for easy integration with PLC, DCS, and fire & gas systems. It is widely used in oil & gas installations, refineries, chemical and pharmaceutical plants, power plants, battery rooms, paint booths, warehouses, and aerospace hangars, ensuring enhanced human safety and asset protection.
