If vibration analysis identifies a fault, would you necessarily see a corresponding increase in ultrasonic readings of the machine (provided you have been doing a trending method)? And, conversely, would vibration analysis necessarily confirm a fault if you see an increased decibel reading through ultrasonic testing? Not always, and that’s just life in the real world. One of the reasons is the variety of ultrasonic sources that can exist in an operating machine. A pump is a good example. There is turbulent flow of the fluid being pumped, there is the possibility of cavitations, there is the metal to grease surface contact, there is the metal to metal surface contact in a bearing, there is the distinct possibility of transient ultrasonic signals – all of which carry ultrasonic energy that can be detected by the ultrasonic detector. Have you ever listened to a pump bearing with your ultrasonic detector and heard a sound like a bearing rotating, then moved your sensor away from the bearing and put it right on the pump and heard exactly the same sound quality? It can get confusing. That’s where field experience, for which there really is no substitute, as well as vibration analysis, come into play. In summary, using Airborne Ultrasound and Vibration Analysis together has its own strength. Many times, one technology can validate the other technology’s findings. But, perhaps more importantly, the combination of technologies gives the inspector multiple sources of information, and a more comprehensive data set, in order to make the proper diagnosis and recommendations.
