Under- and over-lubrication are leading causes of bearing failure. By monitoring the bearing sound level while greasing, ultrasound ensures the right amount of grease is applied.
Compressed air leaks can silently waste a significant share of compressor energy. An ultrasonic survey locates and tags leaks on site.
Benefits
Correct lubrication
Avoid over- and under-greasing.
Energy savings
Compressed air leaks are found.
Very early warning
Bearing faults can be heard before they show in vibration.
Electrical safety
Corona and partial discharge signs are detected.
Process

Frequently asked questions
Does ultrasound replace vibration analysis?
No, it complements it. Ultrasound is especially strong for lubrication, early friction and leak detection; vibration analysis is more comprehensive for determining fault type and severity.
