Design and application of mine-used dust concentration sensor

摘要: 针对现有粉尘测量方法存在无法实时反映现场空气中粉尘浓度的问题，设计了一种矿用粉尘浓度传感器，介绍了该传感器组成、工作原理及其在煤矿自动喷雾降尘装置中的应用。该传感器利用激光散射原理测量悬浮在空气中的粉尘颗粒浓度，同时采用根据粉尘沉降原理设计的精密机械结构和激光镜头刷镜机构，保证了测量的可靠性和精确性。

Abstract: For problem that existing dust measurement methods can not real-timely reflect dust concentration of on-site air, the paper designed a mine-used dust concentration sensor, described composition, working principle of the sensor and its application in automatic spraying device for dust falling in coal mine. The sensor uses principle of laser light scattering to measure concentration of dust particles suspended in air, adopts precision mechanical structure and laser lens brush mirror institutions designed by dust sedimentation principle to ensure measurements reliability and accuracy of the sensor.
