Research on UV Flame Detector

The UV detection technology becomes significant increasingly for the fire monitoring and warning in recent years. However, it is a worthy question to research the actual measurement performance and theory analysis of the UV detection. In this paper the R2868 UV detection of the Hamamatsu company of Japan is researched the whole working principle and the formation process of the response waveform and its influence factors. Experiments show that the maximum number pulse in the unit response time associated with capacitance parameter of power supply circuit. The experimental results and calculation results are approximately identical.
