In a computer-controlled mercury cell plant comprising a cell room, a mercury cell in the cell room, a control room remote from the cell room, and a central control apparatus including a memorized program digital computer arranged to adjust the height of anode banks in the cell in response to analog signals supplied by anode current sensors associated with the banks, a substation is provided in the cell room by means of which the analog signals are multiplexed, digitalized, encoded and serialized before leaving the cell room and are sent to the central control apparatus through a telephonic loop. The substation is preferably situated adjacent a front end of the cell at a distance not exceeding 2 meters. Signal disturbances and use of bundles of cables are thus avoided.
