Training Invitation

Why is it so Important to choose Mobius Training?

Predict Technologies India is a leading Condition Monitoring Company. MOBIUS Institute is a global leader in Vibration Analysis Training and Certification, having certified thousands of analysts in over 60 countries across the world. PREDICT and MOBIUS have come together in an exclusive partnership to offer the world’s leading Vibration Analysis Courses in the market. Predict Institute is the only Institute approved to conduct Vibration Analysis Category 1, 2 & 3 training courses in India.

The Institute is vertically integrated and aims to cater for all who work in NDT, from professor to student and from operator to chartered engineer. Its purpose is to promote the advancement of the science and practice of NDT and all other associated materials testing disciplines – particularly in Condition Monitoring.

In Condition Monitoring and Diagnostic Technology, the ramifications and benefits are enormous. Not only it is safety- Critical but its use enables rectification of an incipient fault before a catastrophic failure occurs. Not only can the physical catastrophe be avoided, but also the financial catastrophe of a major breakdown at the worst possible moment – Saturday night in the printing press of a Sunday paper, or an aircraft engine take-off!

Course Objectives

Perform Vibration Analysis of machinery and components using spectrum analysis Perform impact tests to determine natural frequencies and Resonance. Classify, Interpret and evaluate the test results in accordance with applicable standards. Recommend corrective actions and carry out root cause failure analysis (RCFA). Select the appropriate machinery vibration measurement technique.

Excellent training is an art that is shared by few. Any training organization can develop a lesson plan and execute it. But the best trainers know how to invoke thought and imagination so that it resonates with a student’s mind training and develops better understanding of the subjects. Our course is unique. We use 3D animations, Flash simulations, and numerous software simulators that completely demystify vibration analysis. While vibration training courses have traditionally been very theoretical, you will be captivated by the Mobius Training methods, and you will enjoy our practical approach. You will take away skills that you can immediately apply to your job, and you will truly understand what you are doing.

We also provide quiz questions that help you check if you really did understand the topics, and that you will be able to make the right decisions in the field (and in the exam).

We don’t just deliver an excellent course. We provide you with resources that you can use before, during and after the course.

Mobius Institute Certified Vibration Analysts are authorized by MIBoC to use CVA designation aa part of the their name and MIBoc certification logo as part of their printed and email signature.

Unique aspects about the Mobius Training Course

Get started before the even course starts Before you even start the course you can visit our Learning Zone web site to take the self-paced iLearnVibration lessons (and read through the manual). These lessons will help prepare you for the course – you will learn so much more if you go into the course with this knowledge Don’t stop learning just because the course ends For six months after the course (or longer for a small fee), you can continue to access the iLearnVibration self-paced learning zone material on the web site. If you forget something that you were taught, or you just want a refresher, then just jump on to the site and go through the fully narrated lessons. Course Schedule & Locations:
