NHT Flame detection device of power station boiler of large combustion equipment of furnace safety supervisory system and a variety of industrial furnace,the key equipment of burner flame detection.The device according to the physical properties of the combustion flame detection,When the flame burning state does not meet the normal condition or flameout,it will show signal by some mode (Switch quantity and analog quantity),as logic judgment of the fault alarm or furnace safety supervisory system(FSSS).
Using the latest software and hardware identification technology, with high reliability.
With a self-test function, and has higher safety.
Adapt to all types of fuel, including gas, fuel, coal and other fuel types.
Detection mode, including ion type, light type and image type.
NHT Flame detection device is widely used in electric power,Iron and steel, metallurgy, petrochemical and other industries a variety of boiler,burner flame detection, and also can be applied to various occasions the need for flame detection.

XHT-5 Visible light type flame detector
1 basic configuration:
Consist of probe, flame detector and field regulator(choose ), Widely used in power plants, metallurgy, petrochemical, building materials and other fields of all kinds of fuel, coal burning flame detection, The digital processing technology and the pattern recognition software, hardware, to quantization processing to target flame, improve the accuracy of the detection, independent power supply, reduce the system risk, self-checking function, safe operation.
2 Performance parameters:
Working principle:Target flame by the lens group focused , then through the optical fiber to pretreatment circuit board, Visible light signal is converted to electric signal , then make flame intensity and pulse frequency to be digital processing, finally to flame detector , the CPU of flame detector collect the signals from probe , After treatment, calculate, display the flame intensity and pulse frequency respectively by the digital tube,at the same time display the flame intensity by light pipe , according to predetermined set of fire on , fire off standard toidentify , finally do the corresponding signals and instructions.
There are 2 types of flame detector :
Instrument type , Chasis type
