VCAT-III Vibration Analyst

There are four major reasons why over 4,000 vibration analysts choose Mobius Institute every year:

1. We make complex topics simple with amazing 3D animations and simulations that make you say, “Ah, now I get it!”
2. We give you access to the entire course before the class begins so you are better prepared, and for four months after the course, just in case you still have questions.
3. We use anonymous, stress-free polling throughout the course, so you know if you truly understand each topic, and the instructor knows not to move on to the next topic – no student is left behind.
4. Our Vibration Analysis training is ISO/IEC 17024 and ISO 18436-2 accredited and is globally recognized through the Mobius Institute Board of Certification (MIBoC).

Pre-study:

• Access to the Learning Zone upon registration and payment. For online distance learning, access to the learning platform four months from registration and payment
• Complete set of videos covering every topic
• An excellent way to be prepared and get the most from the course

Post-study:

  with online forums, webinars, tutorials, etc.

There is a great deal to learn, but it will help you to perform your role with confidence. The topics covered in this course include:

• Review of condition monitoring technologies and the ISO standards
• Signal processing and data acquisition
• Time waveform analysis
• Phase analysis
• Dynamics (natural frequencies and resonance)
• Testing for natural frequencies
• Operating Deflection Shape (ODS) analysis
• Modal analysis and intro to FEA
• Correcting resonances
• Rolling element bearing fault detection
• Journal bearing fault detection
• Electric motor testing
• Pumps, fans, and compressors
• Gearbox fault detection
• Corrective action
• Running a successful condition monitoring program
• Acceptance testing
• Review of ISO standards

The key is that on the VCAT-III course you will transition from being a vibration analyst who should be supervised, to a person who is capable of running the program, being a senior consultant, solving difficult problems, and taking a leadership role.

• You should be recognized for your achievements; not everyone is up to the challenge of understanding vibration analysis, let alone successfully collecting data and utilizing it
• Being certified by an accredited certification organization is a major step up from simply passing a test. Yes, the process is a little more complicated and stricter, but that is for very good reasons
• The educational process is extremely valuable, but being certified tells an employer (or a consulting client) that you are capable of doing an important job

Mobius Institute has certified more vibration analysts than any other organization and we have only been offering certification since 2005. Almost 40,000 vibration analysts around the world, just like you, chose Mobius Institute for a good reason.

You will receive a digitally encrypted certificate, an ID card, and a personalized logo that you should use in email signatures and elsewhere that you want people to know about your achievements.

All you need is a desire to learn and to succeed in your field. In order to be certified you must:

• Complete a MIBoC approved training course (click here for a list of approved courses).
• Achieve 70% or higher on the certification exam (100 multiple choice questions, duration 4 hours).
• Have thirty-six (36) months of practical vibration analysis work experience, verified by supervisor/manager.
• Have previously been certified to VCAT-II by a MIBoC approved certification body.

Certification is valid for 5 years.

There is one other way to become VCAT III certified and that is to invoke the mature candidate clause. If you meet the following criteria, you can enter the VCAT training and certification program without being VCAT-II certified. *See below question for criteria:  Can I skip the CAT II course and jump directly to CAT III?
