MVA Training Course

08:00 AM - 05:00 PM

This course is for those individuals with three or more years' experience and who routinely use a data collector. This training course is also partial preparation for the Vibration Analyst Category III Certification Exam. All Vibration Institute instructors are Category IV certified and experienced vibration analysts. Course Instructors are subject to change without prior notification.

MACHINERY VIBRATION ANALYSIS (MVA)

All registered attendees in the Machinery Vibration Analysis training course are provided the two-volume text, Machinery Vibration Analysis: Diagnostics, Condition Evaluation, and Correction, a workbook containing problems and exercises and a ruler. Workshops are scheduled to illustrate theory and applications. This course provides preparation for routine vibration analysis and condition evaluation as well as partial preparation for the certification examination for Vibration Analyst Category III.

It is strongly recommended that individuals review the BMV text Basic MachineryVibrations before attending the MVA course.
