Fluke 805 FC Vibration Meter

The Fluke 805 FC comes with Crest Factor+ which takes the confusion out of bearing assessments. 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.

Import measurements from the 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.

The Fluke 805 FC Vibration Meter is compatible with Fluke Connect Mobile AppFluke Connect with ShareLive™ video call is the only wireless measurement system that lets you stay in contact with your entire team without leaving the field. The Fluke Connect mobile app is available for Android™ (4.3 and up) and iOS (4s and later) and works with over 20 different Fluke products—the largest suite of connected test tools in the world. And more are on the way. Go to the Fluke website to find out more.

Rotating Machinery

The 805 FC enables technicians to confidently track bearing impacting, bearing health, overall vibration level, overall machine health, and bear-ing surface temperature. Its proprietary algorithm known as “Crest Factor Plus” identifies bearing flaws much earlier than simpler vibration meters, and the option to share the results with others in your maintenance team using Fluke Connect® or download the results to an Excel spreadsheet for tracking and trending. It’s a tool you can trust, as its built-in database of overall vibration levels was developed from years of analyzing thou-sands of real machines. The 805 FC is designed to be used by any level technician and take readings during route-based maintenance, which can be screened for changes and potential problems over time. Repair-ing machines before they fail increases uptime while reducing energy waste and maintenance costs.
