The new FL500 optical flame detector (photo) is performance-approved for six different fuel sources: butane, ethane, heptane, methane, methanol and propane. By combining a precision ultraviolet (UV) sensor for quick response with an infrared (IR) sensor that monitors flame-emitted radiation, the FL500 flame detector operates at faster speeds with false-alarm immunity. The FL500 detector offers a wide field of view up to 130 deg and features three external LED indicators for local verification of normal operation, fault conditions and alarms. Designed with continuous optical-path monitoring (COPM), the detector conducts a self-check every two minutes. These optical and electrical self-check diagnostic routines ensure the sensor’s optical path is clear and that the detector’s electronic circuitry is operational. The operating temperature range is –67 to 185°F with a relative humidity range of 0 to 95%, non-condensing. — MSA Safety, Cranberry Township, Pa.
