Abstract
A device for measuring the current amplitude in busbars and other current feeders to the electrodes of a cell for the electrorefining of copper, comprises a Hall generator which can be set with a yoke upon the conductor or bar and which is provided with an amplifier or discriminator circuit operating a display preferably in the form of a linear array of light-emitting diodes.
Claims6
In an electrolysis system in which a current carrier is connected between a current source and an electrode, a device for monitoring the amplitude of the current in said carrier, said device comprising:
- a Hall generator;
- means for mounting said Hall generator on said carrier;
- a direct current source connected to said Hall generator for energizing same;
- an amplifier and discriminator circuit connected to said Hall generator and responsive to an output thereof representing a magnetic field around said carrier;
- a display connected to said amplifier and discriminator circuit for displaying the current in said carrier;
- and
- means for automatically connecting said source upon the mounting of said Hall generator on said carrier.
