DEVICE FOR DETERMINING CONTENT OF ALUMINA IN ELECTROLYTE OF ALUMINIUM ELECTROLYTIC CELL Russian patent published in 2016 - IPC C25C3/20 

Abstract RU 2584631 C2

FIELD: chemistry.

SUBSTANCE: invention relates to electrolytic method of producing aluminium. Device for determining concentration of alumina in electrolyte of aluminium electrolytic cell comprises independent AC voltage source, DC voltage grading, low-frequency electric filter and graphite sensor. At that, independent source of AC voltage is made with possibility of AC voltage supply into circuit of graphite cathode bus-sensor. Output of low-frequency filter is connected to DC voltage recorder, and input is connected to autonomous source of AC voltage.

EFFECT: technical result-increase measurement accuracy and efficiency of determining concentration of alumina.
