CAMSIZER®
德国RETSCH(莱驰)公司多功能粒径及粒形分析仪CAMSIZER是全球唯一一台采用干法及数字成像技术生产的粒度分析仪,它是由RETSCH Technology(德国莱驰兄弟公司)和JENOPTIK JENA(原德国蔡司)联合研制而成。
传统的粒度分析技术(如筛分和激光衍射)存在着多种局限性,如取样量少,样品不具备代表性,粒度分布重现性差,测试过程费时费力,测试数据信息量少,分析结果无法同步等缺点。
CAMSIZER采用了专利的双镜头数字成像技术,基准镜头可测量较大尺寸的颗粒,聚焦镜头则测量小颗粒,颗粒被两个镜头同时捕捉并记录下所有信息,并可在测量过程中实时显示图像。由于其进样量大,因此分析结果极具代表性和重现性。一次进样,在几分钟内,即可得到粒度大小、粒度分布、颗粒个数、形状、球形度、对称性、透明度、凹凸性、表面积、密度等综合信息,其结果也可以和筛分数据进行拟对,毫无疑问,CAMSIZER综合了激光粒度仪、颗粒计数器、图像分析仪、筛分仪等多种粒度分析仪器的功能。

作用原理
The CAMSIZER uses the principle of digital image processing. The sample is transported to the measurement field via a vibratory feeder where the particles drop between an extended light source and two CCD cameras. The projected particle shadows are recorded at a rate of more than 60 images per second and analyzed. In this way every single particle in the bulk material flow is recorded and evaluated. Thus, it is possible to measure a wide range of particles from 30 µm to 30 mm extremely accurately, without having to switch measuring ranges or make adjustments.Thanks to its extremely short exposure times, the novel LED strobe light source allows very sharp images to be produced and distortion-free determination of the projection areas. The sharp contrast allows, at the same time, details of the surface structure of the particles to be seen almost like through a microscope. The frequency of the light flashes is so high that the strobing is not visible to the naked eye.
With the unique, patented two-camera system a great depth of sharpness, and therefore maximum precision across the entire measuring range, is obtained. The zoom camera provides maximum resolution down to the fine range, while the basic camera also records larger particles and guarantees a high statistical certainty in the results. This ensures the excellent reproducibility of the CAMSIZER measuring results, even if only a relatively small sample amount is available. The results are saved in at least 1,000 size classes.

Sample division – as important as the analysis itself
Sample preparation errors can no longer be corrected even by the most up-to-date analytical instruments. This is why Retsch Technology offers a range of sample dividers for obtaining representative part-samples.
