Vibration Analysis ISO Cat. I – Bilbao, Spain

June 19 - June 23

This course is focused on training participants in the detection and diagnosis of the most common problems that are generated in a wide variety of rotary machines using the cull capabilities of the vibration analyzers. The course provides an in-depth study of the typical failures of machinery and its associated spectra, time waves and phase characteristics. Other topics associated with signal processing, data collection and corrective actions are also covered.

Course Goals

At the end of the course, participants will have a broad understanding of the fundamentals of vibration, understand the meaning of all measurement and configuration operations of their data collector, understand the difference between the different types of sensors, how and where to install them or fix them and can analyze vibration spectra, time waves and phase data.

Personnel certified as Category II shall at least perform the following tasks:

  • Define the measurement activities to performed by a category I individual for routine data collection.
  • Be able  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.
  • Perform basic (single – channel) impact tests to determine natural frequencies.
  • Interpret and evaluate  test results from routine analysis and acceptance tests in accordance with specifications and standards.
  • Diagnose common fault indications and recommended basic corrective actions including carrying out single-plane balancing of rigid rotors with or without phase.
  • Provide technical guidance to and instruct category I personnel.
