Reduce downtime and increase productivity by investing in the expertise of your personnel. Vibration Monitoring is a cost-effective strategy for condition monitoring rotating & reciprocating plant.
Who Should Attend
Managers, Engineers, Analysts, Supervisors,Technicians and Operators who wish to learn about basic vibration monitoring and analysis in the areas of Operations, Maintenance, Engineering, Reliability and Condition Monitoring for example from the following industries:
- Aerospace & Aviation
- Facilities, Banking & Utilities
- Food & Beverage
- Manufacturing
- Mining & Minerals, Cement & Fertilisers
- Oil & Gas, Petrochemical & Chemical

- Power Gen, Transmission & Distribution
Course Objectives
This course is based on the ISO 18436-2:2014 certification program for Vibration Analyst Category II & is designed to prepare staff for the Category II Certification Exam. The course is accredited to BINDT PCN CM GEN App D.
VA Category II personnel are qualified to perform industrial machinery vibration measurements and basic vibration analysis using single channel measurements, with or without phase trigger signals, according to established and recognised procedures. They require all the knowledge, experience and skills expected of Category I, and in addition they shall at least:
- be able to define the measurement activities to be undertaken by a category 1 individual in the course of routine data collection;
- be aware of and capable of using the basic principles of signal analysis and, as such, can define acquisition and analysis settings to collect data appropriate to the machine(s) monitored;
- be able to perform basic (single channel) impact tests to determine natural frequencies;
- be able to interpret and evaluate test results and acceptance tests in accordance with specifications and standards;
- be able to diagnose common fault indications and recommend basic corrective actions commensurate with their area of machinery experience including carrying out single-plane balancing of rigid rotors with or without phase;
- be able to provide technical guidance to and instruct category 1 personnel.
Difficulty Level
Intermediate:
Note: VA Cat I Qualification is a pre-requisite for this course.
