The DSI Bearing Diagnostic Unit is a state-of-the-art Condition Monitoring instrument that aids the detection of mechanically deteriorated bearings in operating machinery by detecting the high frequency Acoustic Emissions (AE) signals which are naturally generated by processes such as impacts, crushing and friction in failing rotating equipment. It can also identify problems involving inadequate lubrication or lubricant contamination.
