Forget the pens.

Think METER.

THE

FLUKE 805

VIBRATION METER

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.
