Cat. III- Machinery Vibration Analysis A preparation course for ISO 18436-2:2014 Vibration Analyst Category III Certification Exam

Machinery Vibration Analysis (MVA) is a 5-day in-depth discussions on time waveforms, FFT’s, phase and orbit analysis techniques for the evaluation of industrial machinery. This course is partial preparation for the Vibration Analyst Category III Certification Exam by Vibration Institute.

A Category III Certified Vibration Analyst shall have all the knowledge and skills of a Cat. II VA and be able to provide technical knowledge and instruction to lower level analyst. A Cat. III VA shall have an in-depth knowledge of the principles and techniques machinery vibration analysis including single channel spectra, time waveforms, orbit, basic operating deflection shapes, and acceleration enveloping. They shall be qualified to design, direct, and manage routine condition monitoring programs, to conduct non-routine fault analyses, and to understand and direct alternative condition monitoring technologies to investigate and verify issues not resolved by vibration analysis. The Analyst shall be able to direct machinery corrective actions including rotor balancing and to recommend restrictions in machine operation.

Knowledge Check:

There is a twelve-question multiple-choice workshop supporting each chapter. The student will be provided 30 minutes for each workshop to test their knowledge and understanding of the material presented for that chapter. The instructor will then review the workshop with the class. The student’s time and understanding of the workshop materials will aid them in their preparation for the certification exam.
