alarm level / limits standard ?
alarm level / limits standard ?
(OP)
Can anyone tell me if there is a beginning standard of alarm limits or level criteria on bearings up to 75.5xrpm prior to making my own limits after further trending.What is a good starting point.
Will peakvue be the same or slightly different?

in in/sec
rms peak
Acceptance of new equip <0.8 <0.16
unrestricted operation <0.12 <0.24
surveillance 0.12-0.28 0.24-0.7
Shutdown immediately >0.28 >0.7
RE: alarm level / limits standard ?
PeakVUE is an excellent tool, when properly configured, but it's value is in it's ability to make the bearing-related frequencies more visible in the spectrum while diminishing the high-amplitude frequencies that normally dominate the velocity spectrum. PeakVUE amplitudes have no discernable relationship to the velocity amplitudes measured because it is such a heavily "massaged" or processed signal.
The PeakVUE amplitudes are very dependent on things like the transmission path to the sensor from the source of the energy and the filters and other parameters chosen by the analyst for the measurement.
This is not the definitive answer you may have been looking for, but I hope it is helpful, none-the-less.
