Basic Machinery Vibration (BMV) CAT-2 Vibration Institute USA CAT-2 Certification Exam Prep Course


A unique 5-day weekend course on BMV That prepares attendees to perform basic vibration analysis on industrial machinery using single-channel measurements, with or without trigger signals, according to established and recognized procedures. It covers basics of sensors, database and data collector setup, data collection, signal processing, fault analysis, and basics of single plane balancing. It is partial preparation for the Vibration Analyst Category II Certification Exam. The workshops and demonstrations scheduled throughout the training course are used to illustrate theory and applications.

Key Take-aways

  • Evidence of training in accordance with ISO 18436-2
  • Awareness of key International Standards covering    vibration condition monitoring
  • How to select the correct measurement location and axis, and collect good, repeatable measurement
  • What the Fmax resolution, averaging and other analysis setting mean, and how to select the optimum setting for a wide variety of machine types 
  • How to analyze vibration spectra, time waveforms, envelope (demodulation), and phase measurements 
  • How to diagnose a wide range of fault conditions: unbalance, eccentricity, misalignment, bent shaft, cocked bearing, looseness, rolling element bearings faults, journal bearing faults, gearbox faults, resonance, and other conditions
