Fluke 805

Vibration Meter

The reliable, repeatable, accurate way to

check bearings and overall vibration.

Make go or no-go maintenance decisions with

confidence. 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

What makes the Fluke 805 the most reliable

vibration screening device available?

• Innovative sensor design minimizes measure-

ment 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 prob-

lems for overall vibration and bearing condition

• Exportable data via USB

• Trending in Microsoft

Excel using built-in

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

• Get authorization to take next steps in an instant if

machine health is at risk via Fluke Connect™ Share-

Live™ video call

• 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 naviga-

tion and viewing

What is Crest Factor +? 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. 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.
