September 10–12, 2019: PeakVue™ Mystery and Autocorrelation

PeakVueMystery and Autocorrelation

This 3-day course provides insight into advanced functionality of Emerson’s unique PeakVue™ technology and Autocorrelation. Machine vibrations generate both macro and microscopic vibrations, and microscopic vibrations generate stress waves that have frequency ranges determined by the mass of the impacting object. The properties of these stress waves will be explained. 

The Autocorrelation section of the course will teach the power of the autocorrelation coefficient function for the analysis of vibration induced time wave form data. The autocorrelation function data generally are computed from the same time wave form data used to compute the spectrum. The strengths of the autocorrelation data are complimentary to the strengths of the spectral data. This course makes use of both case studies from real-life examples of common faults and live demonstrations illustrating specific mounting procedures to reliably detect certain faults. The difference between PeakVue™ technology techniques and demodulation will also be demonstrated.



Students should be familiar with vibration data collection and analysis techniques and the use of AMS Machinery Manager Software.
