• Detect impending failures – so that timely, planned
  maintenance can be scheduled before they lead to failure and
  unplanned downtime.
• Reduced periodic maintenance – through reliable knowledge of
  a machine’s health.
• Identify maintenance priorities – critical before a planned
  shutdown when there are pressures on time and resources.
• Understanding the underlying cause of persistent problems –
  allowing effective solutions to be put in place.
                                     Effective condition monitoring programmes optimise
                                     plant asset efficiency, help avoid costly production
