| Abstract Scope |
The monitoring of smelter wedges in aluminium manufacturing plays a critical role in optimizing process security.
Specifically, tracking both temperature and voltage difference across wedges provides valuable insights into the condition of mechanical / electrical contacts.
Wiring of these sensors is not a real option while battery operated sensors would require checking batteries each time before installation and making sure enough energy remains for data measurement and wireless transmission throughout its usage.
A better approach in terms of sustainability and performance is the usage of thermal energy harvesting as the power source for wedges monitoring nodes. Each node contains a supercapacitance as an electrical storage unit and will allow data monitoring, processing and transmission (at 1 minute interval or less) using LoRaWAN wireless protocol.
This dual monitoring approach (temperature and voltage) can proactively identify and address any deviations from optimum, ensuring smoother operations, minimizing manpower while being wireless and batteryless. |
