WHAT WILL YOU GAIN FROM TAKING THIS COURSE?
—
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 with 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
