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

摘要

A method to control a process of magnetic removal of ferromagnetic impurities from loose, liquid and gaseous media by determining degree of purification by relative change of resistivity of sensors, through space between which plates the medium to be cleaned is passed, the sensors are interconnected by a bridge electrical circuit, and with a unit of measurement - differentially. The housings of filter and remote sensors of determination of specific resistance of filter medium are grounded against action of external electrostatic fields.
