CAMSIZER®
The CAMSIZER is a compact laboratory instrument for simultaneous measurement of particle size distribution, particle shape and additional parameters of powders and granules.
Based on digital image processing by the unique, patented two-camera system pourable solids in the range from 30 µm to 30 mm can be measured.
Thanks to the unique scanning of all particles and the newly developed fitting algorithms, the measuring results are 100% compatible to those of sieve analysis. This makes CAMSIZER the ideal time- and cost-saving alternative for incoming and outgoing controls and for in-process quality control.
In combination with the optional AutoSampler efficiency can be increased by high sample throughput due to the automated sample measurement.
For online applications the CAMSIZER is available in an online version.
Application Examples
abrasives, carbon products, catalysts, coffee, fertilizers, foodstuffs, glass / ceramics, metal powders, pelletized carbon black, pharmaceutical materials, plastics, polystyrene, refractory products, salts, sand, sugar, ...

Function Principle
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.
Subject to technical modifications and errors
CAMSIZER® versus sieve analysis – maximum benefits from minimal efforts
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.
