Dynamic Image Analysis System Particle Size

Dynamic Image Analysis (Digital Image Processing) is an established method, along with sieve analysis and laser diffraction for particle size analysis in the measuring range 20 µm to 30 millimeters. This method is superior to the others in its resolution, precision and reproducibility and delivers additional detailed particle shape information.

 

CAMSIZER P4®

The CAMSIZER® P4 is a compact laboratory instrument for simultaneous measurement of particle size distribution and particle shape, number and density of powders and granules. The patented design is the only one to use two cameras and greatly extends the measurement range while maintaining accuracy and sensitivity throughout.

The dual camera system of the CAMSIZER P4 is superior to any other dynamic image analyzer in terms of width of size range, analysis speed, accurate shape detection and resolution. It provides optimized analysis conditions for small and large particles without compromising resolution or detection probability. Therefore, wide range measurements with no hardware adjustments can be reproduced with precision

Application Examples:

Application Examples: abrasives, carbon products, pelletized carbon black, coffee, catalysts, fertilizers, food products, glass/ceramics, metal powders, pharmaceuticals, plastics, polystyrene, refractory products, salt, sand, sugar, and many others.

 

Product Advantages:

  • Improved data correlation to sieve analysis, including multi-modal distributions.

  • Sample optimized, intuitive software.

  • Additional shape parameters including sphericity, aspect ratio, convexity, symmetry, roundness, elongation, circularity, and surface texture analysis.

  • Language versions including English, German, French, Japanese, and Spanish.

  • Wide Size Range: 20 µm to 30 millimeters in one measurement with no hardware changes required; a 1500:1 dynamic range.

  • Measurement Principle: The instrument employs digital image processing to measure size, shape, number and density of solid particles.

  • High Resolution: Two linked, high resolution, full-frame cameras, with different resolutions, operating simultaneously, form an intelligent measuring system with a very wide dynamic range while still capturing images of all particles in the sample.

  • Monitor the particle size distribution with real-time calculation during the measurement

  • Image acquisition at 60 frames per second

  • High-intensity, long life stroboscope LED light source 

  • Automatic sheeting air to keep camera and light source windows clear of dust

  • Automatic measurement chamber vacuum eliminates velocity biasing by maintaining equal particle velocity independent of size, shape or density 

  • Sample introduction via automatic speed-controlled vibratory feeder

  • Automatic feeder hopper height control

  • 30 seconds to 4 minute analysis time, depending on sample type

  • ISO-traceable certified calibration reticle with a particle size distribution of 60 microns to 14 mm (maximum inaccuracy of 0.1 microns per object).

  • Every particle is analyzed from each pixel to each other pixel in all orientations before binning into 64 classes.

  • High resolution analysis in at least 1,000 up to 3,000 saved, size classes per run.

  • Ten user-selectable measurement size models for superb correlation to particle width, particle length or equivalent area to get excellent correlation to results from laser scattering, hand caliper measurements and sieve analysis.
