Dynamic Image Analysis (DIA)

The CAMSIZER X2 uses the principle of digital image processing. The patented principle is fairly simple: Dispersed particles pass in front of two bright, pulsed LED light sources. The shadows of the particles are captured with two digital cameras.

One camera is optimized to analyse the small particles with high resolution, the other camera for the detection of the big particles with a good statistic, that means large field of view. Each camera is illuminated by one LED with optimized brightness, pulse length and field of view. A user-friendly software analyzes the size and shape of each particle, and finally calculates the respective distribution curves in realtime.
