Powerful fault detection and trending methods

One of the most powerful yet simplest method to detect faults and trend frequency band data is Constant Percentage Bandwidth spectral data (Octave and fractional-octave). We have refined the Octave Band method in order to increase its effectiveness while still keeping its simplicity . This will be particularly useful in those situations where the number of machines is large and the complexity of the machines is not high. That method is also not too sensitive to small speed changes.

Trends can be performed on overall (RMS, peak, peak-to-peak, crest factor and kurtosis) or frequency band data. Inspection notes and historical data can also be super-imposed on the trending curves. From a given trending curve, VIBREXPERT can also extrapolate the time required (or date required) to attain a given vibration level. Warning, alert and alarm levels can be specified for each measurement point and many reports on machinery condition are available, in order to obtain a good appreciation of the general condition of a group of machines.
