It is the earliest indicator for detection of faults that can lead to asset failure.
Ultrasound refers to any sound pressure wave with a repetition frequency greater than 20 kHz. Ultrasound tester is a highly effective non-destructive and predictive maintenance tool in condition monitoring field that enables the operator to detect compressed air or vacuum leak detection, electrical corona discharge identification in electrical panels, switch yards etc, steam traps and lubrication check to improve the bearing life in rotating machinery. It is recommended by entities such as the U.S. Department of Energy as the best method for detecting the location of leaks in order to minimise energy waste and improve plant efficiency.
