ISO Category II Vibration Analyst - Intermediate

This course is intended for people who have mastered the basics but who need to be able to take good data (and decide how the data collector should be set up), analyze a range of fault conditions, and understand balancing and alignment.

We teach you 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 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 come away from the course with a solid understanding of:

How a well-designed program and a reliability centered maintenance approach improve the OEE and therefore the bottom line
The condition monitoring technologies: acoustic emission, infrared analysis (thermography), oil analysis, wear particle analysis, & motor testing via supplementary training
How machines work; via supplementary selfstudy using the “Equipment Knowledge” section
How to select the correct measurement location and axis, and collect good, repeatable measurements
What the Fmax, resolution, averaging and other analyzer settings mean, and how to select the optimum settings for a wide variety of machine types
How to analyze vibration spectra, time waveforms, envelope (demodulation), and phase measurements
How to diagnose: unbalance, eccentricity, misalignment, bent shaft, cocked bearing, looseness, rolling element bearings faults, journal bearing faults, gearbox faults, resonance, and other conditions
How to set alarm limits manually and with statistics
How to balance and align a machine, and correct a resonance condition

Through this Certification Course, participants have the opportunity to accrue 5 Continuing Professional Development (CPD) points.
