  • <a href="http://www.fluke.com/fluke/inen/home/default.htm" title="Fluke Corporation-India">Fluke</a> redefines mechanical troubleshooting with a revolutionary product: The <a href="http://www.fluke.com/fluke/inen/products/categoryvibration" title="Vibration Testers">Fluke 810</a> is designed specifically for maintenance professionals who need to troubleshoot mechanical problems and quickly understand the root cause of equipment condition.
  • Vibration screening devices provide quick feedback of equipment condition A single number for overall vibration to understand whether there is a problem, instead of analyzing vibration in-depth with a spectrum.If the machine vibration or noise is higher, this value will increase.
  • Crest Factor:1 to 5                Good ( One Bar )6 to 10              Satisfactory ( Two Bars )11 to 15            Unsatisfactory ( Three Bars)16 & above       Unacceptable (Four Bars )
  • Crest Factor is defined as ratio of peak value/RMS value of a time domain vibration signal.Key limitation - it does not increase linearly as the bearing degradesVery difficult to determine the severity of mechanical issues.Crest Factor can actually decrease as a bearing nears catastrophic failure due to large RMS values.CF+ values range from 1 to 16. As bearing condition worsens, CF+ value increasesEnsuring the user is easily able to recognize the severity of the problem. To make things even simpler, Fluke has also included a four-level severity scale that identifies the bearing health as Good, Satisfactory, Unsatisfactory or Unacceptable.
  • For the severity scale, you must set the Meter to recognize the type of machine, or Machine Category, for the test. A list of the most common categories is programmed into the Meter. When the Meter is set to a category, it can adjust for the usual vibration levels of different machine types. This gives you the best accuracy in the severity scale.After these parameters are set, the Meter shows the overall vibration and bearing measurements with a severity scale for each measurement. The overall vibration severity scales use a statistical analysis of data from thousands of industrial machines. Keep in mind when you use the severity scales:• The severity scales are only applicable to machines at speeds from 600 RPM to 10,000 RPM.Make measurements with the accelerometer as close as possible to the bearing housing.• The severity scales are not applicable if the machine is installed on spring or pad isolators.• Severity scales for motors match the machine that they operate. For example, when you do a test on a motor that operates a centrifugal pump, select the applicable centrifugal pump Machine Category for all test points on the motor and pump.• Gearbox severity scales are applicable only for single stage, rolling element bearing gearboxes.
  • The 805 supports an optional external sensor.Any standard ICP type single channel accelerometer connected via a Subminiature version B connection should work.Make sure that the sensor is securely mounted on the machine.CF+ and temperature measurements will not be collected, just overall vibration.

    1. 1. Fluke 805 Vibration MeterRedefining Vibration Screening 1
    2. 2. Types of Vibration TestingSimple vibration screening: Overall vibration/bearing measurements• Use vibration screening tools to make quick “go” or “no go” decisions by checking the value against a pre-set alarm level, comparing it to ISO Standards (ISO 10816) and trending the results over time. 2
    3. 3. What does it measure? 805 Vibration Meter is Fluke’s multifunction vibration checker which • Provides quantifiable results of bearing condition, overall vibration, temperatur e - • Assesses the severity on a severity scale • Provides ability to upload the data to PC for later trending 3
    4. 4. The Problem The SolutionProblem: Confusing“I don’t understand what Problem: Not enough datathe numbers mean. “Vibration pens do not provideWhat indicates a enough data to provide goodproblem?” value to a ‘true’ reliabilitySolution: program.”STRAIGHTFORWARDFour-level severity scale Solution:both overall vibration A COMPLETE SOLUTIONand bearing condition A meter—not a pen—thatusing measures overall vibration,textual alerts bearing condition and(Good, Satisfactory, temperature reliablyUnsatisfactory,Unacceptable) 4
    5. 5. The Problem The SolutionProblem: Unreliable“The pens only work well whenapplied exactly correctly andthey’ve caused a lot of falsealarms mostly because oftechnician error.”Solution: RELIABLEInnovative sensor design,force sensor and tip angleensure quick readings &consistent results: Angle andpressure has minimal impacton results(Patent pending) 5
    6. 6. The Problem The SolutionProblem: Manual“The data from the pen needs to fit into ourexisting operator rounds tracking program,which means I need to be able to upload itto Excel—easily.”Solution: DATA LOGGING• View previous measurements in device• Export to Excel for trending• Comparison to ISO Standards 6
    7. 7. The Problem The SolutionProblem: Difficult“They’re a pain to use—I have to Problem: Fragileinput a lot of data—not just RPM “Made of light-weight plastic. I feelrange and type of equipment but like it will break the first time that Ishaft diameter and actual RPM.” drop it”Solution: EASY Solution: RUGGED• Sensor sensitivity to a wide • Made of tough, heavy plastic. range of frequencies covering • Feels solid and well-balanced in most machine and your hand. component types,• Minimizes the user inputs to RPM range and equipment type.• Green light indicating right amount of pressure is applied 7
    8. 8. Fluke 805 redefines vibration screening• Performs in low frequency range to measure overall vibration and in high frequency range to identify bearing faults.• Assesses severity on a four-level scale for both overall vibration and bearings.• Uses the new and innovative Crest Factor Plus algorithm. 8
    9. 9. What is Crest Factor +?• A proprietary, weighted calculation involving several waveform parameters, such as the Crest Factor, the Peak value, and the RMS value algorithm used to identify bearing faults. 9

    11. 11. How to use the 805 • Supports an optional external sensor • Any standard ICP type, (100 mV/g) single channel accelerometer • If external sensor is connected, the users will be able to measure only overall vibration (no CF+ and temperature measurement) 11
    12. 12. How to use the 805 • The meter has an audio connector for headphones – useful for detection of unusual machine sounds. • Press and hold the measure button to listen with sensor tip pressed against bearing. 12
    13. 13. Benefits of Trending with Vibration Meter • Export measurements to Excel template on PC to trend overall vibration, CF+, and IR temperature. • Looking at the number alone for the overall vibration or bearing condition might not be of much benefit • What is normal or what indicates a problem? • 805 users can use the severity assessment and trending functionality to overcome this obstacle. 13
    14. 14. Benefits of Trending with Vibration Meter• After operator rounds, trend with preconfigured Excel plot graphs and compare to ISO Standards (10616-1, -3 and -7).• If there is an abnormality, it can be identified by using the trend charts.• The user can now see a clear picture of the changing bearing condition and deteriorating health of the machine 14
