The Theory of Infrared Thermography

Infrared imaging cameras show us how heat is being radiated from and transferred through equipment and structures . By analyzing these heat signatures, we can acquire more information about your equipment and structures than by the visual eye.

Until a failure brings them to your attention, problems which normally remain hidden can be found early and causes identified. Corrective action taken will save you money, inconveniences and may just save a life. Conditioned monitoring of equipment can be accomplished by doing A thermal infrared imaging analysis periodically. Infrared Thermography imagers "see" the heat radiated from the surfaces of your operating equipment in real time, just like a video camera sees visible light. When heat images, called thermograms are in color, usually the white,yellow and red areas are hotter and the black and blue areas are cooler depending on the color palettes the technician chooses to use.

When performing an infrared inspection, valuable information can be acquired in order to apply a predictive maintenance program to your company. Some applications exist where numeric temperature data is not required to diagnose the problem. In these cases, qualitative techniques can provide you the information that is needed. Most applications, however, require numeric temperature data in order to classify the severity of a problem.

Comparative thermography can be used to provide the best available data in lieu of ideal thermal measurement capabilities. Changing load considerations, techniques in performing rough emissivity estimates, and the ability to differentiate emissivity differences on energized or rotating equipment give the thermal infrared technician the ability to provide useful information under the less-than-ideal circumstances frequently encountered in the field.!

One of the first signs that something is going wrong in your equipment, will be the emission of excessive heat. This heat can be detected with infrared imaging thermography. With one pass of the camera, the "hot-spots" point out the problem areas on your equipment. This technology works on a wide array of applications.
