Abstract
We present a measurement system where a spherical permanent magnet is levitated in an actively controlled magnetic field. The sensor system measuring viscosity and density independently. In operation mode, the magnet is held in a constant levitation position. Due to a special actuation scheme, the magnet rotates around its vertical axis. Using this setup and immersing the magnet in a fluid, it is possible to analyze viscosity and density of all kinds of fluids, except ferrofluids. The magnetic levitation system avoids any connection penetrating the walls of the measurement chamber; only the spherical permanent magnet measurement body is in contact with the sample fluid. Due to this, the measurement procedure is reproducible, repeatable and resource saving.
