SharpEye^TM20/20Land20/20LBUV/IR Flame Detector (BIT)

·Using a UV sensor that is insensitive to sunlight and an additional narrowband infrared sensor,

·It can provide excellent detection sensitivity and improve immunity to false alarms (light blindness).

·Provide high-speed and high-performance flame detection and alarm for military and industrial industries.

·Can detect combustion flames of hydrocarbons, such as hydrogen, hydroxyl compounds, as well as metal and inorganic combustion flames.

·Monitor narrowband spectral frequencies of ultraviolet and infrared radiation.

·The sensor ensures a high sensitivity to the emission spectrum frequency generated by flames, while also having immunity to the emission spectrum frequency generated by non combustible micro smoke.

·The UV sensor integrates logic circuits to prevent false alarms caused by sunlight radiation.

·The detection range of the IR sensor is 2.5~3.0 microns. The detector analyzes the frequency, brightness, and duration of the signals received by UV and IR sensors, and any sensor can trigger an alarm upon receiving the flame emission spectrum.
