Abstract

Large alumina electrolysis baths operate at high electrical current and high temperature hence a number of safety hazards. Conventional safety inspection relies on manual temperature monitoring using IR remote thermometers, which is not in real time and not reproducible. This paper presents a distributed fiber optic temperature sensor (DTS) system based on Raman scattering principle. The operation principle and method of deployment of the DTS system in an alumina electrolysis base and on-site monitoring results are discussed. The field measurement results show that the accuracy of the measurement of the distributed fiber optic temperature measurement system meets the application requirements and have great application potential.
