Design of Wireless Material Level Sensor Nodes for Alumina Storage Bins of Aluminum Electrolysis Plant

Article Preview

Abstract:

A wireless level sensor system was designed aiming at solving data acquisition issues on material level measurement of alumina storage bin towers. Using the high performance MCU, STM32, and 433MHZ wireless communication modules, the wireless nodes were developed. New measuring method based on weighing sensors was proposed to adapt to the severe environment of storage bins full of thick dusts and high-density magnetic field. Experiments and actual measurement in factory environment were performed and indicated the stability and reliability of the wireless material level measuring system.
