Why Do I Need to Use Time Waveform Analysis?

January 16, 2018

Condition Monitoring Expert Tip #7 by Mobius Institute Spectrum analysis provides a great deal of information about the health of rotating machinery. But you should consider the spectrum as a summary of the vibration within the machine. The Fast Fourier Transform takes the time waveform and computes how much of each frequency is present and […]

How to best determine vibration monitoring intervals for critical machinery

June 24, 2013

To appropriately determine monitoring intervals a couple of things must be known. First,  the point in time (P) that the potential failure becomes detectible must be known (detected with vibration monitoring,  etc.). Second, the time (F) at which the potential failure would degrade to a functional failure must be known. This difference in time (P-F Interval) […]

Myth and Truth Detecting Machinery Failure

April 11, 2011

MYTH:  A well-trained technician can predict within a window of a few hours when a machine will fail. TRUTH: This myth is common throughout industry and poses a danger to machinery.  The myth often leads to operating machinery with known defects for periods longer than is safe for the equipment.  Let’s explore the elements that brought […]
