An increase of the surface temperature on operating equipment is often an indication of machine health degradation. However, there are pitfalls in simply looking for hot spots.

Did you know that:

• Not all problems are hot

• Equipment with an internal fan may give inaccurate thermal readings

• Over-lubrication is as much of a problem as under-lubrication


Thermal cameras have evolved from a specialist-only device to an ideal tool for process equipment maintenance—from troubleshooting to scheduled maintenance. By using a thermal camera for troubleshooting, the technician can diagnose the root-cause more efficiently while also often identifying other potential problems during the same inspection.


Check out this article and learn what to look for and how to capture the best images during thermal inspections.
