    The field of Predictive Maintenance has developed around the desire (or is it requirement?) to know when machinery is likely to fail. If you can see the future early enough, the equipment can be repaired during a scheduled downtime instead of causing a catastrophic failure at an inopportune moment. There are many different ways to monitor the conditions of equipment, but thermography is certainly one of the most popular.

   Thermography provides a heat sensitive picture of an object. By comparing the results of thermographic images over time, changes in the temperature of objects can be detected and analyzed to determine if failure is likely. The nice thing about this is that most objects, whether mechanical, electrical or fluid-based, exhibit some type of heat increase before failing.    When electrical connections become dirty or corroded, they resist current, which creates heat. This heat increases the rate of corrosion, which increases the heat, until the circuit catches fire. In mechanical devices, lubrication, alignment and vibration problems create friction or require more power, both of which produce heat. Fluids also become hotter if their path is obstructed in any way.

   Thermography can also detect failures in the insulating properties of materials. If the seals on your home windows are failing, this will show up as heat around these areas. A common application is called refractory analysis. Over time, the bricks that line a furnace wear down. As they do, the walls get very hot. The earlier this heat can be detected, the earlier it can be dealt with. One company that is very strong in this area is Inframetrics, Inc. of Billerica, MA. Recently, the company introduced three new infrared camera systems. These new models, the ThermaCAM PM180, PM280, and PM 380, have a number of features that Inframetrics believes separate them from other products of this type.

   On the PM 280 and PM 380 models, a third key is the ability to store up to 400 images on removable 80 MB flash memory cards. Each image is stored in a proprietary, 12-bit grayscale format. Using software, these values are converted to meaningful temperatures. Normally, these temperatures range from 10 degrees Celsius to +450 degrees. The PM 380, however, can be used in environments with higher temperatures. By itself, knowing that there is a change in temperature doesn't tell you exactly when a failure will occur. However, that probably isn t the most critical point. The goal is to have the time to repair the problem before it gets out of hand, and this has made thermography a very popular tool for predictive maintenance.
