Acoustic Emission and Vibration
Engineering and Construction
Pages 4 (1004 words)
Both acoustic emission and vibration sensors have been applied in the development of several monitoring systems that have been conditioned due to their early detection application when it comes to faults arising due to important machinery components
The process of early detection has proved to be a very crucial factor in condition monitoring as well as serving as a basic extended CBM component (Zamada and Masuda, 1999, p. 160). Though the two sensors are effectively applied in this process, there exist several differences in their applications as well as a number of advantages and disadvantages over each other. The acoustic emission normally abbreviated as AE refers to sound waves that are normally produced in the event that a material is subjected to stress due to internal changes and external forces. A good example of this phenomenon is the mechanical loading which generates elastic wave’s sources (Lokajicek and Sikula, 1996, p. 312). Over the years, acoustic emission has steadily replaced the use of vibration techniques that were used traditionally. This transformation is closely associated with the better working conditions witnessed while working with acoustic emission. Vibration sensing has been associated with a number of mechanical conditions such as processes that result in energy loses like friction and impacts, machinery deteriorates, and frequencies that come in a broad range. Acoustic emission on the other hand makes use of much higher frequencies when it comes to vibration movements that are synchronous. ...
