Condition Monitoring with Airborne Ultrasound for Grid Couplings
Using airborne ultrasound is a great method for condition monitoring grid couplings. Although vibration analysis can be effective at identifying 1x shaft speed and harmonic frequencies in the velocity spectrum, it’s hard to determine whether the forcing frequency is due to misalignment, imbalance, or damage...

Finding Heat Exchanger Condenser Tube Leaks with Ultrasound
Heat exchangers come in many shapes, sizes, and configurations. Their purpose; to efficiently transfer heat energy from one medium to another while keeping those media separate. Sometimes called “surface condensers”, these installations are used in a variety of industrial applications. We find them in refineries, water...

The Hidden Costs of Over-Greasing — And How to Stop It
Walk into almost any plant and you will hear it. If a little grease is good, more must be better. That belief has quietly cost industry millions. Over-greasing does not protect bearings. It creates excess pressure, increases friction, raises operating temperatures, and pushes grease past seals....
