The Intermediate Vibration Analysis course is intended for personnel who have at least twelve months vibration analysis experience and a thorough understanding of vibration theory and terminology. Eighteen months of vibration analysis experience is required for Category II or Level II certification. The course provides an in-depth study of machinery faults and their associated spectrum, time waveform and phase characteristics.
A Category II analyst is expected to know how to test machines correctly, how to diagnose faults accurately, perform additional diagnostic tests for verification, how to set vibration alarm limits, and how to correct certain types of faults. You need to understand what your analyzer settings mean so that you can take the best measurements. You also need to understand why the vibration patterns change the way they do and how to use time waveform analysis and phase
analysis to verify the fault condition.
- We teach you to test machines correctly, how diagnostic tests for verification, how to set vibration alarm limits, and how to correct
certain types of faults.
- You will learn what your analyzer settings mean so that you can take the best measurements. And you will learn why the vibration signatures change the way they do and how to use time waveform analysis and phase analysis to verify the fault condition.
- You will learn how to analyze vibration spectra, time wave-forms, envelope (demodulation), and phase measurements
- You will learn how to diagnose: unbalance, eccentricity, misalignment, bent shaft, cocked bearing, looseness, rolling element bearings
faults, journal bearing faults, gearbox faults, resonance, and other conditions
- You will learn how to balance and align a machine, and correct a resonance condition
WHO SHOULD ATTEND
If you have been performing vibration analysis for more than six months, and feel that you have a good understanding of the fundamentals, then you are ready to step up to Category II course. (Note that 18 Months experience is required to be certified). Anyone who wants to be capable of confidently diagnosing a wide range of fault conditions, correcting certain conditions, and taking accurate measurements needs to take this course. Many plant sites require contractors to be certified and many employers require employees to be certified. The Mobius Institute course and certification program follow the ISO 18436-2:2003 standard and the ASNT Recommended Practice SNT-TC-1A.
