山东风途物联网科技有限公司生产的β射线扬尘检测仪可自动测量和记录浓度，采用的是贝塔射线吸收法的工作原理，将C-14作为发射源，其发射恒定的高能量电子，样品空气通过切割器以恒定的流量经过进样管，颗粒物截留在滤膜上。β射线通过滤膜时，能量发生衰减，通过对衰减量的测定计算出颗粒物的质量，根据采样流量、采样时间和滤膜面积来计算实际状态下环境空气中颗粒物的浓度。该设备适用于建筑工地、道路施工、工厂厂界等颗粒物的在线监测。
The beta ray dust detector produced by Shandong Fengtu Internet of things Technology Co.,Ltd.can automatically measure and record the concentration.It adopts the working principle of beta ray absorption method.The C-14 is used as the emission source,which emits constant high-energy electrons.The sample air passes through the sample tube with constant flow through the cutter,and the particles are retained on the filter membrane.Whenβ-ray passes through the filter membrane,the energy is attenuated.The mass of particles is calculated by the measurement of attenuation.The concentration of particles in the ambient air is calculated according to the sampling flow,sampling time and filter membrane area.The equipment is suitable for on-line monitoring of particulate matter in construction site,road construction,factory boundary,etc.
