Fluke 805 FC with Crest Factor + Takes the Confusion Out of Bearing Assessment

The original Crest Factor is used by vibration analysts to identify bearing faults. It is defined as the ratio of the peak value/RMS value of a time domain vibration signal.

A key limitation of using Crest Factor to identify bearing faults is that the Crest Factor does not increase linearly as the bearing degrades. In fact, the Crest Factor can actually decrease as a bearing nears catastrophic failure due to large RMS values.

In order to overcome this limitation, Fluke uses a proprietary algorithm known as Crest Factor + (CF+). CF+ values range from 1 to 16. As the bearing condition worsens, the CF+ value increases. To keep things simple, Fluke has also included a four-level severity scale that identifies the bearing health as Good, Satisfactory, Unsatisfactory or Unacceptable.

Export and Trend in Excel

Trending, or repeated vibration measurements kept in a spreadsheet over time, allows you to better track machine health.

Sample Trend Plot

Import measurements from the 805 FC Vibration Meter to an Excel template on your PC in order to trend the bearing parameters include overall vibration, CF+, and temperature. Looking at just the number alone for the overall vibration or temperature might not be of much benefit to the operator or technician if they do not know what the number means. The user may not know what is normal or what indicates a problem.

If measurements taken on the operator's rounds are easily loaded into Excel, then the trend will show patterns of something that is becoming abnormal. The user can now see a clear picture of the changing bearing condition and deteriorating health of the machine.
