Airborne Ultrasound
|
Ultrasound inspection is a valuable tool for predictive and preventive maintenance, energy management and quality control. The way in which ultrasound is used in preventive maintenance is relatively simple. Ultrasonic detectors are sensitive to sound beyond the limits of normal human hearing (20 Hz – 20,000 Hz)., and therefore can "hear" faults in rotating machinery, electrical distribution systems, and leaks in vacuum and pressurized systems.

 An infrared thermography program using appropriate equipment and properly trained thermographers can be an extremely effective tool to optimize equipment and system efficiencies and help diagnose existing or potential failures of electrical, mechanical, refractory and building envelope related systems.

In electrical applications, airborne ultrasound can detect corona which exists above 1 kV and which does not generate any heat. Infrared therefore can not find the existence of corona which if left unattended will further develop into a tracking and arcing situations. Ultrasound allows a more comprehensive electrical inspection and when used with infrared, the inspector can then identify corona, tracking, arcing, and resistance problems in any electrical equipment.
An ultrasonic detector senses small changes in the ultrasonic signature of a component and accurately pinpoints potential sources of failure before they cause severe damage to the components. Ultrasonic translators provide information in two ways: "qualitatively," through their ability to detect ultrasound and convey it through a noise isolating headphone, and "quantitatively" through visual and incremental readings on a meter.
Airborne Ultrasound is very useful in Compressed Air Leak Survey, Gas Leak Detection, Steam Traps Survey, Bearing Condition Monitoring, Electrical Inspection, Bearing Lubrication, and Unpressurized Leak Detection.
