20/20ML - Mini UV/IR Flame Detector

The low cost, compact, lightweight 20/20ML UV/IR Flame Detector comprises both UV and IR sensors, detecting hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires at distances up to 50 ft (15 m).

List of Benefits

  • UV/IR Dual-Sensor
  • High-Speed Response
  • 50 msec Response to Saturated Signal
  • Large Field of View (100° horizontal/vertical)
  • User Programmable Functions Configurable via software from a PC or handheld device
  • Immune to False Alarms (solar blind)

The UV sensor incorporates a special logic circuit that helps prevent false alarms caused by solar radiation. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.
