Which is the Best Bearing Fault Detection Technique?

December 5, 2017

Condition Monitoring Expert Tip #5 by Mobius Institute Now this is a tricky question to answer… We have a few contenders: high frequency vibration analysis, regular vibration analysis, ultrasound, oil analysis, wear particle analysis, and infrared analysis. Let’s start by ruling a few of them out. Infrared analysis is used to detect heat in a […]

Is your Application FIT for Ultrasound?

September 26, 2017

I often hear the question, “what can I detect with ultrasound?”. The fact is, ultrasound is such a versatile condition monitoring technology we tend to ask it to do things beyond its capabilities. And that’s fine because I firmly believe every technology should be pushed beyond its limits. It’s how we get better. But to […]

Ultrasonic Signature can Provide early Warning of Mechanical Failure

February 21, 2017

Rotating equipment produces a sound (ultrasonic) signature during operation. This signature can be measured and trended over time. As the machine components begin to fail a change in the ultrasonic signature will occur. The change in sound level can be used to alarm that could be related to lubrication or bearing damage. A key factor […]

Complementary Condition Monitoring Boosts Reliability

January 10, 2017

As Published by COMPRESSORtech2 Magazine October 2016 issue by Karl Hoffower – Condition Monitoring and Reliability Expert for Failure Prevention Associates Combining ultrasound and vibration sensing adds precision to recip valve analyses Over the past decade, ultrasonic condition monitoring of reciprocal compressor valves has become more widely known. However, it does not seem to be widely used. Ultrasonic testing measures high-frequency sound waves, […]

Labeling Ultrasound Data Collection Points

December 13, 2016

To facilitate the initial learning curve, a labeling system was implemented to help technicians collecting data identify bearings that were part of the initial survey. These descriptors were laminated to prolong their life in the unfriendly environment of a typical cement plant. Standard locations for data collection needed to be understood since labels would become […]
