Abstract

Filter of linear beam smoke detector is the supporting equipment for linear beam smoke detector. The study of its filtering characteristic and calibration method is developed for value transfer technology in new material development industry and the measurement technology of key parameter in key areas, as well as laying foundation in special detection method, improving the quality of industrial product and proposing improvement plan of overall technology, which is necessary for constructing the measurement support system and supporting the development of service industry. In this paper, calibration method of filter for linear beam smoke detector is studied, including attenuation value of light, uniformity of attenuation value, difference between positive and negative attenuation values. It ensures the effective traceability of filter for linear beam smoke detector and makes the work of smoke detection traceable.
