Hydrogen Flame Detector

The FL500 from MSA designed for the protection of oil/gas refineries, chemical plants, fuel stations, and other sites managing large volumes of the gas.

2004np Msa

The Ultraviolet/Infrared (UV/IR) flame detector is designed to detect hydrogen (H2) fires, monitoring optical radiation emitted by a hydrogen flame in both the ultraviolet and infrared spectral ranges while at the same time rejecting nuisance false alarm sources common within industrial job sites. The detector’s flame sensing technology relies on the UV sensor to provide a quick response (<3 seconds) and the IR detector monitors radiation emitted by a flame over a wide 130-degree field of view. UV/IR sensor technology offers increased immunity, operates at faster speeds, and is suited for both indoor and outdoor use. Output options include instant and timed fire alarm relays, 4-20 mA analog output with HART, and RS-485 Modbus RTU. The detector also supports HART revision 7 and is fully FieldComm compliant. It features an automated self-check of its optical path and electronic circuitry; every two minutes built in self-check technology performs an optical and electrical check to ensure the optical path is clear and the electronic circuitry is operational. Approvals include: CSA, ATEX, IECEx, and CE Marking. Classifications include: Class I, Div 1, Groups B, C, D; Class II, Div 1, Groups E, F, G; Class III, Type 6P; Ex db IIC T5 Gb; Ex tb IIIC T100°C Db II 2 G D; and IP66/IP67.
