The Fluke 805 Vibration Meter is the most reliable vibration screening device available for frontline mechanical troubleshooting teams that need repeatable, severity-scaled readings of overall vibration and bearing condition.
Fluke 805 with Crest Factor + takes the confusion out of bearing assessment
The original Crest Factor is used by vibration analysts to identify bearing faults. The Fluke 805's Crest Factor 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.
Exporting and Trending with the Fluke 805
Trending, or repeated vibration measurements kept in a spreadsheet over time, is the best method to track machine health. With the Fluke 805 Vibration Tester you can easily:
Export your result to Excel through USB connection
Trend the readings with the pre-built Excel templates and plot graphs
ompare the overall vibration readings to ISO Standards (10816-1, 10816-3, 10816-7)
Import measurements from the Fluke 805 Vibration Meter to an Excel template on your PC in order to trend the bearing parameters: 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 don’t know what the number means. The user may not know what is normal or what indicates a problem.
If measurements taken on the operator 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.
