METHOD FOR CONTROL OF PROCESS OF MAGNETIC REMOVAL OF FERROMAGNETIC IMPURITIES FROM LOOSE, LIQUID AND GASEOUS MEDIA

摘要

A method for control of process of magnetic removal of ferromagnetic impurities from loose, liquid and gaseous media by determining degree of cleaning by relative change in inductance of electric coils, through which a medium to be purified is passed, interconnected by a Maxwell bridge circuit, and with a unit of measurement - differentially. A housing of filter and remote sensors for determination of the inductance of filter media are grounded against action of external electrostatic fields.
