摘要：

This paper presents the development of circuits that are used to provide excitation and reception in ultrasonic transducers for the generation of guided waves in hollow cylinders for fouling detection. Fouling is a problem that has been present in the chemical, petroleum, food, and pharmaceutical industries. It consists of the deposition of heavy organic materials and other dissolved solids or the suspension in fluid transport systems. The ultrasonic guided waves present specific characteristics and have demonstrated good results in the detection of flaws in pipelines. The circuits are presented, and experimental results are discussed.
