Sensing: in the know

摘要

Frank Ansuini and Jim Dimond, Electrochemical Devices, Inc., USA, explain how to fight corrosion with innovation. The use of multi-sensor arrays for underground corrosion control Is a cost-effective method for providing several different types of data that more fully characterise conditions at the structure. The multiple data types available from such sensors when monitoring oil and gas pipelines and other buried structures, support the latest direct assessment techniques. Each of these data types is determined independently but, collectively, they provide a more complete picture of the corrosion activity. This article will briefly describe the types of sensors used and provide two examples where they have proven to be valuable tools for the corrosion engineer.
