Measurement Instrumentation for Aluminum Electrolysis Cell

With the continuous development of aluminum electrolysis production processes, traditional manual measurement methods can no longer meet the requirements for efficient and precise production. This study developed an industrial embedded measurement system based on an ARM processor to automatically measure the height and temperature of molten aluminum and electrolyte in aluminum electrolysis cells in real time while providing high-precision data feedback. The system integrates temperature, impedance, and displacement sensors, ensuring measurement stability and accuracy in complex electrolysis environments through multisensor fusion and optimized signal processing algorithms. To address interference factors such as strong magnetic fields and high temperatures present in aluminum electrolysis cells, the system employs electromagnetic compatibility techniques to ensure long-term stable operation under harsh conditions. Moreover, the embedded system features high scalability and flexibility, enabling customization for different electrolysis cell configurations and diverse application requirements. Experimental results demonstrate that the system achieves high accuracy and stability, effectively supporting real-time monitoring and precise control in the aluminum electrolysis production. This work provides a novel approach for intelligent aluminum production.
