Abstract :
This article describes new application area for the magnetic field with spatial components of multiple frequencies - displacement measurement. Most level-meters for liquids and loose materials require accuracy not more than millimeters for several meters range with hard working conditions. The most effective way is to apply eddy-current gauge with periodic (sine) function of displacement to electric signal transformation. The article presents the method and structure of level-meter based on traveling magnetic field with multiple frequencies of spatial components.
