Five Minute Facts
Detecting Bearing Faults Using Condition Monitoring Software
There are many faults that cause a rotating component to breakdown and fail, some of the most common being misalignment, unbalance and soft foot. One of the most common faults that cause a component to breakdown are bearing defects.
Why would a company carry out condition monitoring programs?

Making It In A High Frequency World Striving for High-Frequency Industrial Accelerometers
As predictive maintenance teams in industrial facilities strive for a more complete picture of their equipment’s health, high frequency vibration measurements have become a crucial addition to identify faults such as motor and pump bearing defects and gear tooth inconsistencies in high-speed gearboxes. As a result, there is an upsurge in demand for vibration sensors with a high frequency response.

Why MEMS Accelerometers Are Becoming the Designer’s Best Choice for CbM Applications
A small number of semiconductor manufacturers have overcome the noise, bandwidth and g-Range shortcomings commonly associated with MEMS sensors used in Condition-based Monitoring (CbM) by producing several medium and high-performance MEMS vibration sensors with the latter being comparable to piezo accelerometers.

How to Diagnose the Root Cause of an Overheated Gearbox
This session will show you how to find commonly misdiagnosed or overlooked issues. A case-study example of a medium-sized gearbox with a seemingly obvious lubricant failure will be presented to illustrate how data can identify a lubricant selection problem. Attendees will learn how to apply this knowledge to future oil analysis reports so they can correctly diagnose the true root cause of an alarmed condition.

Rotor Bar Fault Maintenance Issue: Vibration Sensor Alert
A 398 KW MV motor that runs a blower fan in a cement plant was showing strange behavior. The vibration equipment indicated vibration amplitudes that became chronic with the passage of time. The maintenance team, not knowing what the issue was, ran the motor until the bearings had to be replaced...
