Magnet tracking of particles in fluidized and spouted bed processes

The magtrack is based on the Magnetic Marker Monitoring. It was developed for the recording of the motion sequences in closed systems, in order to analyze and optimize such processes. With the magtrack it is possible to detect the absolute orientation in a defined space of the magnetic marked particles. The magtrack-System has a modular design and can be adjusted to most equipment and a variety of systems.



The magtrack measurement method is based on a 3D localization of a magnetic marker. At this point the real-time measurement shows the tracking of the motion of a magnetically marked object. The comprehensive and fast evaluation of the particle trajectory, with a sample rate up to 1,000 Hz is done offline, so that precise and statistically reliable conclusions about the overall process can be made.

The main advantage of the magtrack system, compared with other methods, such as PIV (Particle Image Velocimetry) or PEPT (Positron Emission Particle Tracking) is a non-contact, non-optical and non-ionizing-radiation based measurement method. In addition to the 3D trajectory, magtrack always provides the orientation of the particle for every position.
