AI Technical Summary
In existing technologies, temperature and voltage measurements in aluminum electrolysis cells are separate and cannot be synchronized or measured at the same point. Furthermore, they are susceptible to stray currents and electromagnetic interference, leading to inaccurate data and increased system complexity.
A thermocouple for synchronous temperature and voltage measurement was designed. It uses a metal conductive sheath containing a positive and negative thermocouple core and a conductive wire. The core is insulated and isolated by insulating filler, and the voltage signal is led out through an independent conductive wire. Electrical isolation is achieved by connecting the connectors, forming an anti-interference dual signal channel.
This method enables synchronous and simultaneous measurement of temperature and voltage within the aluminum electrolysis cell, reducing stray current interference, improving measurement accuracy and system reliability, and lowering complexity and safety risks.
