NDHJ-5 The Integrated Intelligence Flame Detector

1.summary

NDHJ-5 The integrated intelligence flame detector is our company follows the international newest fire to examine and dispatch unfolds the tendency independent development a section new flame detector .Does it based on the microprocessor technology and the numeral field bus technology, whether there is judge and the strong and the weak through the examination flame frequency and the luminous intensity, has the intelligent judgment, the network, the miniaturization and the online software promotion function, is suitable large-scale boiler flame examination which in the coal-burning, the fuel oil, the fuel gas and so on each kind of burner arranges. The MFDPro intelligence integration flame detector will be examines the intelligent integration flame detector based on the microprocessor which the gauge head and the signal processor will combine. It through to flame burning intensity and frequency judgment flame burning condition, through scene specialized installment and correction, but shields the adjacent angle, the opposite angle background flame disturbance effectively.It does not need two time signal processors or the amplifier, does not need the fire to examine the amplifier cabinet, even may abbreviate the massive scene wiring.Not only this may install the debugging cost economical, also enable the examination system the whole movement reliability to obtain the enormous enhancement.

3.Function

-The sustainable electronic self-checking function, and can output the breakdown node signal. But long-

distance/adjusts the flame ON/OFF threshold value;

-But long-distance/adjusts the flame gain multiple;

-But long-distance/adjusts the flame frequency range;

-Outputs the 4-20mA combustion intensity signal;

-May output has the fire/to misfire the node signal;

-Entire Chinese operation contact surface, in entire Chinese position machine software;

-All parameters can carry on the installation through the scene/long-distance two ways.
