<p>A process for the remote transmission and indication of measured values of a plurality of electrolysis cells, comprising sequentially interrogating the measured values in the electrolysis cells by means of an electronic pulse counter and an electronic check-point reversing switch connected to the pulse counter, transmitting the measured values in the form of an analogue signal to a separate monitoring facility common to said cells, and controlling the electronic pulse counter at the electrolysis cell from the monitoring facility by switching pulses or a pulse series, a maximum of four signal wires being provided between each electrolysis cell and the monitoring facility irrespective of the number and type of check points.</p> |
