Machinery Health - PeakVue™ Mystery and Autocorrelation , 2035 - Emerson Course

Specific for:


This 3-day course provides insight into advanced functionality of Emerson’s unique PeakVue and PeakVue Plus 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.

Autocorrelation will teach the power of correlated waveform analysis. The same time waveform used for autocorrelation is used by the FFT to generate the spectrum. The strengths of the autocorrelation data are complimentary to the strengths of the spectral data.

 This course makes use of case studies from real-life examples of common faults and live demonstrations illustrating specific mounting procedures to reliably detect certain faults. Comparisons between PeakVue technology techniques and demodulation will also be demonstrated.


Students should be familiar with AMS Machinery Manager software, fundamentals of the AMS 2140 and conventional vibration data collection and analysis techniques.


  • Proper PeakVue technology set-ups for all speeds (as low as 1 rpm)  
  • Sensor selection and sensor mounting  
  • Setting alarm levels  
  • Choosing trend parameters  
  • Analyzing PeakVue technology spectra and waveforms  
  • Uses of the circular waveform plot
  • Introduce the autocorrelation coefficient
  • Highlight the strengths of the autocorrelation coefficient function data relative to spectra data
  • Demonstrate the use of the autocorrelation coefficient data as a diagnostic tool to support the spectra data for vibration analysis through several case studies.
  • Identify unique patterns of the autocorrelation function data for certain classes of bearing faults, gearing faults, etc.
