Predictive Maintenance (PdM) is a process by which a maintenance technician is alerted to a problem developing in a critical production machine. If a PdM program is run successfully, this alert gives enough warning not only to determine what the problem is but also to order the parts and schedule the people necessary to repair it. Ideally, this warning would also provide the luxury to schedule the maintenance during a planned outage rather than at an inopportune time. This, in a nutshell, is how Predictive Maintenance programs work and they have been used successfully in many industries for decades.

There is a wide selection of vibration monitoring systems out there ranging from simple walk-around models to the most advanced online continuous monitoring systems. Typical vibration monitoring instrumentation involves accelerometers, switches, 4-20 mA transmitters, cables, junction boxes and other accessories.

But the main components to a vibration monitoring system are:

  • Sensors, including cables and junction boxes
  • Data collection device
  • Monitoring/analysis software

IMI Sensors offers a wide variety of sensor options for use with all popular data collection devices.
