The CAMSIZER P4 analyzes particle size and shape of dry, free flowing bulk materials in a size range from 20 μm to 30 mm via Dynamic Image Analysis (ISO 13322-2).

 

The software controlled feed chute conveys the sample to the measurement zone, ensuring uniform sample feed and consistent analysis conditions. The particle stream passes an ultra-bright planar LED stroboscopic light source; the resulting shadow projections are captured and evaluated by a camera system. The particles fall freely during analysis, so the procedure is contact-free and non-destructive.

 

The CAMSIZER P4 particle analyzer provides extremely sharp images and determines a variety of different size and shape parameters for each detected particle. Analysis of hundreds of thousands or even millions of individual particles guarantees results with high statistical reliability. The typical measurement time is only 1 to 3 minutes with 60 images being evaluated per second in real time.

EXTREMELY WIDE MEASURING RANGE DUE TO UNIQUE DUAL CAMERA TECHNOLOGY

Microtrac MRB’s unique dual camera technology is a landmark in the development of Dynamic Image Analysis (DIA). By simultaneously employing two cameras with different magnifications, extremely wide dynamic measuring ranges are archieved. This is accomplished without hardware adjustments or modifications and without compromising accuracy.

 

Each camera is specialized for one measuring range. The ZOOM camera analyzes fine particles with highest precision whereas the BASIC camera detects the larger particles with great statistical certainity. A special algorithm combines the information provided by both cameras and delivers the exact size distribution in a possible range of more than three decades!

 

This arrangement resolves a significant drawback of many image analysis systems that employ only one camera, e. g. microscopes. Such instruments either cannot correctly report the fine particles in wide size distributions, or the large particles are not captured due to the small field of view.

MEASUREMENT PRINCIPLE

Two cameras operate during measurement: the BASIC camera (red) analyzes the larger particles, the ZOOM camera (blue) captures the small particles. This procedure ensures optimum measurement conditions for all particle sizes in a distribution.

Traditional sieve analysis frequently forms the basis for quality standards and product specifications between suppliers and customers. A rapid and efficient alternative like Microtrac MRB's CAMSIZER systems must take this into account and be able to produce results that are fully comparable.

 

This is why the CAMSIZER P4 software is provided with algorithms for emulating sieving processes.

 

In this way many users have been able to replace time-consuming sieve analysis by using the CAMSIZER P4 without having to sacrifice the familiar quality specifications. The automated and wear-free measurement means that the results obtained are more reliable and reproducible over time.

BETTER RESULTS IN LESS TIME

THE ADVANTAGES OF THE CAMSIZER P4 IN COMPARISON TO SIEVE ANALYSIS

Sieve analysis is a well-known method for particle size characterization. While it is easy to carry out, it does take several process steps, is highly time consuming as well as error prone. We have a created a brochure to help decide why you should consider switching from sieving to dynamic image analysis to get better results in less time.

THE AUTOSAMPLER 

CAMSIZER P4 IN CONTINUOUS OPERATION

The Autosampler is a fully automatic sample feeding system for the CAMSIZER P4 which can be easily retrofitted to existing instruments. It processes up to 14 samples (extendable to 40 samples) in a row without the need for the operator’s intervention. The correct measurement settings are read from the barcodes on the sample beaker. The Autosampler is suitable for continuous operation.

FUNCTIONAL PRINCIPLE

The particle analyzer CAMSIZER P4 uses the principle of dynamic image analysis (ISO 13322-2). The sample is transported to the measurement field via a vibratory feeder where the particles drop between a planar 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 almost every single particle in the bulk material flow is recorded and evaluated. Thus, it is possible to measure a wide range of particles from 20 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 dual-camera system optimum measurement conditions over the entire size range and therefore maximum precision is obtained with the particle analyzer. 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 3,000 size classes.
