Fluke 805 FC Mechanical Machine Vibration Meter Tester

Fluke 805 FC Vibration Meter

The reliable, repeatable, accurate way to check bearings and overall vibration. Make go or no-go maintenance decisions with

Make go or no-go maintenance decisions with confidence. The Fluke 805 FC 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.

What makes the Fluke 805 FC the most reli- able vibration screening device available?

• Innovative sensor design minimizes measurement variations caused by device angle or contact pressure
• Consistent data quality at both low and high frequency ranges
• Four-level severity scale assesses urgency of problems for overall vibration and bearing condition
• Exportable data via USB
• Trending in Microsoft® Excel using pre-built templates
• Overall vibration measurement (10 Hz to 1,000 Hz) for acceleration, velocity and displacement units of measurement for a wide variety of machines
• Crest Factor+ technology provides reliable bearing assessment using direct sensor tip measurements between 4,000 Hz and 20,000 Hz
• Compare vibration levels with ISO-10816 severity scales and store results to the Fluke Connect Cloud
• Colored lighting system (green, red) and on-screen comments indicate how much pressure needs to be applied to take measurements
• Temperature measurement with Spot IR Sensor increases diagnostic capabilities
• On-board memory holds and saves up to 3,500 measurements
• External accelerometer support for hard to reach locations
• Flashlight for viewing measurement locations in dark areas
• Large screen with high resolution for easy navigation and viewing

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.
