MAGNETIC SHIELDING FOR MEASURING A PLURALITY OF INPUT AND/OR OUTPUT CURRENTS TO AN ELECTROLYTIC CELL

摘要

The present invention relates to a system and method for monitoring, in real time, the electric current that passes through each one of a plurality of single cathodes or anodes forming an electrolytic cell. The system comprises a plurality of sensor means including Hall Effect sensors. The sensor means are arranged for current measurement and thermal drift correction. Such sensors are located in a sensor bar which includes a protecting shield which provides magnetic shielding and also prevents corrosion. The present invention enables a more accurate measurement of the current of each electric unit within the electrolytic cell (cathode or anode) by using a ferromagnetic barrier acting as a magnetic shield in order to reduce the effects of magnetic fields adjacent to the target one and by correcting the measurement based on heat factors that may alter the measurement.
