Research and Design of IUR76-I Test System for Ultraviolet Flame Detectors
UR76-1 performance test system for ultraviolet (UV) flame detectors is based on the National Standard of P.R.C,which is named as performance requirements and test methods for point ultraviolet flame detectors (GB12791-1991). The architecture of new test system includes of ultraviolet point source,optical track,modulator,optical filter device,4-dimension holder,optical simulators,data collector,and computer. The common test is consisted of response threshold measurement,response characteristic curve measurement,direction measurement,surrounding optical interference test,and power on test. In the new test system,deuterium lamp is used as the ultraviolet point source to replace the fire of the combusting gasified gasoline,which is used in national standard. The stability of deuterium lamp is smaller than 0.05%,which is much better than 20% (stability of the combusting gasified gasoline). The optical filter device is equipped with stepper motor. There are four bands ultraviolet waves could pass through optical filter device,which are 200nm~ 280nm wide band,2J0nm narrow band,254nm narrow band,270nm narrow band. The data collector and computer software is used in new test system to analyze measurement results and obtain quality reports for DUT. Based on the experience procedure and results,the new test system is proved more convenient,safe,and precision than the system proposed by national standard. This new test system for ultraviolet flame detectors is applied in testing the point ultraviolet flame detectors equipped in industrial or civilian buildings.
