Pennsylvania-based General Monitors has announced the introduction of a new FL500-H2 Flame Detector designed to enable the safe use, production and transport of hydrogen.

The new flame detector has been specifically designed for the protection of oil/gas refineries, chemical plants, fuel stations, and other sites managing large volumes of the gas.

The FL500-H2 sensors monitor optical radiation emitted by a hydrogen flame in both the ultraviolet (UV) and infrared (IR) 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 ultraviolet sensor to provide a quick response (<3 seconds) and the infrared 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.

The design of the FL500-H2 Detector features a compact footprint for ease of installation along with a rugged stainless-steel housing. The easy-to-read display includes three LED indicators that show normal operation, fault condition, and an alarm.

The FL500-H2 provides a number of alarm signalling output options including instant and timed fire alarm relays, 4-20 mA analogue output with HART, as well as RS-485 Modbus RTU. The FL500-H2 also supports HART revision 7 and is fully FieldComm compliant.
