【Abstract】 The application of CO 2 sensing technique to measurement of current efficiency of an Al electrolytic tank is a new technical scheme for energy saving and capacity increasing. The ceramic capacity type sensitive elements made by high temperature sintering have stable physical and chemical properties. The CO 2 density measuring device can convert CO 2 density into transient electrical signal. The electrical signal is processed by a computer, obtaining transient current efficiency value.更多还原
