Leakages of pressurized air or other gases are often causing additional costs and can sometimes be even dangerous. Localizing such leakages by ear is normally hard or even impossible, because the ultrasonic emissions are inaudible to the human ear, especially in industrial environments. Here the Acoustic Camera enables maintenance personnel to accurately detect leakage sounds even far into the ultrasonic frequency range.
Another application for the Acoustic Camera is in predictive maintenance. While experienced maintenance experts can sometimes hear the difference between a smoothly running machine and a faulty one, they mostly can't properly localize the abnormal sound. Less skilled personnel might not even hear the difference. When using the Acoustic Camera for predictive maintenance the measurements can be compared to previously recorded acoustic images of "good" machines and differences showing errors and damage are immediately obvious. Corrective measures can be implemented to prevent further damage and downtime.
Sometimes damages or faulty parts in a machine are noticed by maintenance personnel or internal sensors, but can't be accurately localized. In this case the machine needs to be shut down for lengthy diagnostic procedures or parts are exchanged on a trial-and-error basis. A costly process that can be avoided by using the Acoustic Camera to localize and exchange only the parts really causing the malfunction. Defective parts often generate different and louder sounds than good parts. The Acoustic Camera can be used to exactly localize defective parts like bearings, gears, shafts, etc. and help pinpoint the root cause of malfunctions.
