Vibration Data: Eliminating Poor Vibration Data Samples

By Jude Iyinbor CEng.

Vibration monitoring to aid machinery fault identification, without unnecessary intrusion into machinery internals, has seen a lot of benefits from fault prediction to reduced downtime.  However, some plant managers, reliability, and maintenance personnel still find it challenging to maximize the value of a Machinery Vibration Analysis program.  The quality of vibration data collected from a given piece of equipment is one of the most important criteria to consider when looking at ways to maximize the value of any vibration analysis program. 

Poor vibration data is a set of data that is not a true representation of the actual signature taken from the machine during normal operation.  There are several causes of poor vibration data including:

  • A damaged accelerometer due to heavy impact or broken circuit on cabling
  • The machine not running when data collection occurs
  • The wrong data collection point being used
  • Not allowing for sufficient settling time and abrupt end to the data collection process
  • Poor data collection surface selected
