Abstract

A system, device, and method include a cell-powered first electronic device for monitoring two or more electrolytic cells is powered using electrical potential imposed across the electrolytic cells. The potential is voltage-boosted to accomplish this task. If the electrical potential imposed across the cells is insufficient, the device can also be battery-powered. In any event, this device is in communication with one or more sensors in the electrolytic cells, as well as a second electronic device, and the first and second electronic devices wirelessly communicate. More specifically, the first electronic device wireless transmits data signals to the second electronic device, which receives the same. The first and second electronic devices are physically remote from one another, and they communicate over a private or public network, preferably using spread spectrum technology. In addition, the second electronic device also preferably transmits data signals to a computer for further processing of the data signals, and these arrangements can be used, for example, when producing copper.

Claims
