Abstract

Hall-Héroult potlines are very inefficient and inadequately outfitted with sensors, mostly due to safety concerns around sensor wires between pots, possible interference with existing hardware, and the lack of an easily-accessible, maintenance-free, continuous power source for the sensors. We present a tested solution to accurately measure various process parameters via wireless sensing technology, specifically Berkeley motes running TinyOS, using the cells' waste heat as a thermoelectric power source. Early experiments at Eastalco indicated that the motes, with a few modifications, will be able to operate reliably in industrial conditions, successfully transmitting radio packets, despite the plant's strong magnetic fields, at distances of over 100 feet. This paper describes the successful testing of wireless measurements of several cells' parameters, discusses what other measurements are feasible and appropriate, and describes the energy-scavenging thermoelectric power sources.
