Low Speed Vibration Measurements

Low Speed Vibration Measurements

This presentation looks at low speed vibration measurements and the challenges of using accelerometers to accurately reproduce low speed (<600 rpm), low amplitude vibration signals. The relationship between acceleration, velocity and displacement is explained and a comparison of the voltage levels for the same signal is investigated. The importance of dynamic range and noise floor parameters is described as well as their influence on the results.

3 Key Learning Points:

  • The importance of sensitivity
  • The role dynamic range plays
  • The significance of noise floor values
