  • Engineering units vs. Decibel notation
  • Time and Frequency Domain concepts
  • Signal types - Stationary and Non-stationary
  • Vibration severity in practice
  • Lin/Log scaling of data

MEASUREMENT INSTRUMENTATION

  • Vibration transducers - principle of operation and applications
  • Signal conditioning
  • Vibration amplitude measurement
  • Frequency analysis - when/why/how?
  • Filters and an Introduction to FFT analyzers
  • Rules for signal analysis


BASIC APPLICATION EXAMPLES - Spectrum

Analysis

  • Rotating machine fault diagnosis
  • Fundamental requirements for successful fault diagnosis
