AN OVERVIEW OF THE PREDICTIVE MAINTENANCE APPLICATIONS OF AIRBORNE ULTRASOUND TESTING

Detection of Low Frequency (around 40kHz) Ultrasound is a powerful method for maintenance inspection of plant and machinery. Many failure conditions give early indication by the production of ultrasound. These include pressure leaks, electrical discharge and deterioration of bearings and other machi...

Summary:Detection of Low Frequency (around 40kHz) Ultrasound is a powerful method for maintenance inspection of plant and machinery. Many failure conditions give early indication by the production of ultrasound. These include pressure leaks, electrical discharge and deterioration of bearings and other machinery. Leakage of compressed air has become a particular issue recently with the promotion of energy / CO2 emission reduction initiatives - most estimates suggest that in excess of 5% of industrial energy use represents wasted compressed air. This talk will briefly discuss the operating principles and typical equipment, and give detailed examples of industrial, transport, military and aerospace applications.
