Forget the pens.
Think METER.
THE
FLUKE 805
VIBRATION METER
![](asset-2.png)
The Fluke 805
is not a vibration
pen; it’s a meter.
A Fluke meter
that eliminates
the confusion
of vibration
screening and
provides reliable
measurements
you can trust
to make critical
go or no-go
maintenance
decisions.
FOOLPROOF instead
of false alarms
REPEATAB LE instead
of random
EASY instead
of confusing
You told us about your frustrations with vibration pens and other similar
devices. We listened, and the Fluke 805 Vibration Meter is our answer—
a more reliable, more user friendly tool to improve your routine mainte-
nance checks. To demonstrate how our vibration meter solves the problems
commonly found with other screening tools, we matched actual customer
quotes with Fluke 805 functions. Read on below and see if we make a
believer out of you.
The PROBLEM with vibration pens The SOLUTION The Fluke 805
UNRELIABLE
“Vibration pens are fine for what they
are. We check whether the machine
exceeds the alarm level or not. But that
is pretty much it. It does not provide us
a clear picture of machine condition.
They do not provide enough data to
provide good value to a ‘true’ reliability
program.”
RELIABLE
A meter—not a pen—that measures
overall vibration as well as specific
variables like bearing condition
and temperature to provide a more
complete picture.
INCONSISTENT
“The pens only work well when
applied exactly correctly and they’ve
caused a lot of false alarms mostly
because of technician error. I want a
measurement I know will be consis-
tently reliable, no matter which of my
guys is taking it.”
REPEATABLE
A combination vibration and force
sensor tip that compensates for user
variance (force or angle) yielding
accurate, repeatable readings.
MANUAL
“The data from the pen needs to fit into
our existing operator rounds tracking
program, which means I need to be
able to upload it to Excel—easily.”
AUTOMATED
Data management capabilities for
matching existing equipment IDs and
exporting data to Microsoft® Excel for
trending over time.
CONFUSING
“I don’t understand what the numbers
mean. What indicates a problem?”
STRAIGHT-FORWARD
A four-level severity scale for
both overall vibration and bearing
condition using textual alerts
(Good, Satisfactory, Unsatisfactory,
Unacceptable).
DIFFICULT
“They’re a pain to use—I have to input
a lot of data—not just RPM range and
type of equipment but shaft diameter
and actual RPM.”
EASY
One tool with sensor sensitivity to
a wide range of frequencies (overall
vibration 10 Hz to 1,000 Hz, bearing
condition 4,000 Hz to 20,000 Hz)
covering most machine and component
types, and a straight-forward user
interface that minimizes the user inputs
to RPM range and equipment type.

Features and benefits
• 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 scale indicates severity of problems 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
• Colored lighting system (green, red) and on-screen comments indicate
how much pressure needs to be applied to take measurements
• Infrared temperature sensor increases diagnostic capabilities
• On-board memory holds up to 3,500 measurements
• Audio output for listening to bearing tones directly
• 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
Export and trend in Microsoft® Excel
Trending vibration measurements over time is the best method to track
machine health.
With the Fluke 805 you can easily:
• Export your results to Microsoft® Excel
through a USB connection
• Trend the readings with the built-in
templates and plot graphs
• Compare 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. The user can now see a clear
picture of the changing bearing condition
and deteriorating health of the machine.

Crest Factor+
(High Frequency Measurement)
The original Crest Factor technology 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 iden-
tify 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 identi-
fies the bearing health as Good, Satisfactory,
Unsatisfactory or Unacceptable.
