Active magnetic levitation and 3-D position measurement for a ball viscometer [PDF]

Journal of Sensors and Sensor Systems, 2016
We present a new technique for 3-D position sensing and active magnetic levitation of a steel ball for use in a levitating ball viscometer. In order to achieve a stable levitation, a very sensitive positioning measurement system is mandatory.
