Vibration Analysis ISO CAT II
The ‘Intermediate Level’ Category II course is ideal for those who are interested in condition monitoring to ensure the reliability of their machinery, and who have either, completed a VA Cat I, or have significant vibration analysis experience, including an understanding of vibration theory and terminology.
The course provides an in-depth study of machinery faults and their associated spectrum, time waveform and phase characteristics.
Additional topics covered include signal process, signal analysis data collection and proactive measures.
Course Information
Duration: 4.5 days
Plus 3-hour optional extra 3rd party certification exam through SPM Academy. 70% passing grade. Available at an additional cost.
Format: Classroom learning
Compliance: Follows ISO 18436-2 and 18436-3 and provides 3.5 Continuing Education Unit (CEU) credits.
