What is Predictive Maintenance?

I talk alot about thermal imaging being part of a predictive maintenance plan. So what exactly is predictive maintenance? What makes it different from preventative maintenance? And lastly, which is more cost effective - predictive maintenance or preventative maintenance?

What is Predictive Maintenance?

Predictive maintenance is a way to evaluate your current equipment to determine its condition so you can predict the optimimum time to perform maintenance. The goal is to perform maintenance when maintenance activity is most cost-effective and before the equipment loses performance within a threshold. Most Predictive Maintenance inspections are done while your equipment is in service so your normal system operations aren't disrupted. Thermal imaging scans are an ideal way to do predictive maintenance on your equipment.

Predictive Maintenance is different from preventative maintenance which is usually performed on a set schedule based on usage statistics or time. Preventative maintenance is done regularly whether it is needed or not.

Preventative Maintenance is labor intensive, ineffective in identifying problems that develop between scheduled inspections, and therefore is not as cost-effective as Predictive Maintenance. On the other hand, since Predictive Maintenance inspections are performed while your equipment is in service, you minimize the disruption of normal system operations as well as labor costs, result in substantial cost savings and higher system reliability.


Infrared thermography is used for the predictive maintenance of mechanical, electrical, and building diagnostic systems. Some specific examples include:


  • motors

  • pumps

  • bearings

  • compressors

  • conveyor idlers

  • loose connections

  • corrosion

  • load imbalances

Implementing an infrared thermography program as part of your predictive maintenance is easily justified by its ROI.
