UV/IR Flame Detector

The SENSE-WARE UV/IR Flame Detector is a combination of an Ultraviolet- and Infrared- Flame detector which utilizes a microprocessor for sophisticated electronic signal analysis. The IR part of the flame detector has an additional alarm criterion: the analysis of the flame flicker- frequency. The UV and the IR sensor must both exceed their alarm threshold to initiate a fire alarm. The UV/IR Flame Detector has good false alarms rejection capabilities because the Ultraviolet sensor and the Infrared sensor do not share false alarm sources. The UV/IR Flame Detector can therefore be applied in areas where single UV or IR flame detectors could potentially cause false and/or unwanted alarms. To prevent unwanted alarms, the dynamic delay time for an alarm is 4-8 seconds depending on the size and or the distance to the flames. The UV/IR Flame Detector is suitable for applications that include Hydrogen but in fact, every flame that emits hot water will be detected. A self-test is performed every hour to make sure the sensor and electronics operate well. A Test Lamp is available for regular inspections and end-to-end testing.
