During the process of electrolytie extraction of metal from aqueous solutions, short-eireuiting eleetrodes could reduceeletrolysis current efficieney, inerease power consumption,and reduce the quality of cathode produets. The change of electrodecurent is the most effective way to monitor electrode short circuit. Due to the harsh electrolysis environment, the complexelectromagnetie field distribution, and the large number of electrodes, there are curmently lack of effeetive online eleetrode currentmeasurement methods. This paper proposes a method of measuring electrode current, which uses a linear Hall sensor to detect themagnetice induetion under the electrode in real time. The decoupling mathematical model among the Hall potential, magnetic induetionand current is utilized to caleulate the current flowing through the conduetive rod. In the laboratory, conductive rods are used insteadof electrodes to build an electrolytie cell for testing. Results show that when the total current flowing through the conduetive rods varieslinearly between 10 and 100 A, the current of a single conduetive rod measured by the proposed method is comparable to the clamp.The deviation of the measured value of the shape meter is within 1 A. And the measurement eror is within 2%.The currentmeasurement system has high accuracy and ean be used for on-line measurement of electrode currents in electrolyzers of metal aqueoussolutions such as copper and zine.
