Five main benefits:
1/ When you
register for this course, you will be given access to the Mobius
Institute Learning Center where you can access iLearnVibration,
the manual, and the pre-study guide. Prepare and you will succeed!
2/ Our
course utilizes modern slides, animations, innovative
simulations, and live case studies -
all delivered by Walt Barringer, Alan Friedman, or Tony DeMatteo, who are all very experienced analysts and
instructors.
3/ Each
class will have ten Dell notebook computers so that you can
interact with the simulations, participate in course activities,
and analyze real vibration measurements.
4/ You can
take the optional certification exam. The training course and
exam follows the ISO 18436.2 Category II standard, and the ASNT
SNT-TC-1A Level II standard.
5/
You can continue to use iLearnVibration for six months after the
course, and you take a way our pocket Reference Guide,
diagnostic mouse pad, and our new training manual.

Intermediate Vibration
Training
ISO Category II / ASNT Level II
The Vibration Analyst "Intermediate"
course is intended for personnel who have at least twelve months
vibration analysis experience and a thorough 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 topic covered
include: signal processing, data collection, and corrective active
actions.
You will come away with a very good
understanding of the fundamentals; you will understand the meaning
of all of the measurement options on your data collector; you will
understand the difference between the sensors types, and know how
and where to mount them; and you will feel comfortable analyzing
vibration spectra, time waveforms, envelope data, and phase data.
