New compensation ferrometer design

Aleš Havránek – Ivan Zemánek

   The compensation ferrometer is an instrument for the measurement of open specimen soft magnetic materials parameters at AC magnetization based on the magnetomotive force compensation method. New magnetizing process regulator that controls voltage induced in measuring winding (magnetic flux density waveform) and the voltage induced across Rogowski-Chattock potentiometer(compensation) was developed recently. This paper deals with a new compensation ferrometer design that allows taking the full advantage of the new regulator. New ferrometer based on STEMlab platform improves precision and speed of the measurement.
