A method for the continuous temperature measurement of an aluminun electrolyzer
Quan Zhang · Industrial Instrumentation & Automation · 2001
This paper presents a method for the continuous temprature measurement of an aluminum eletrolyzer by using a temperature balancing principle.Through a negative feedback technique,a thermocouple can be put outside the aluminum electrolyzer to determine its inner temperature.An initial experiment shows that this method makes it possible to perform such a temperature measurement with high accuracy and low cost.The method is expected to find wide use in the metallurgical industry.
