Understanding Infrared Thermography Technology
Fundamental Principles
Infrared thermography represents a non-destructive and non-intrusive testing process employed as predictive maintenance inspection technique to detect abnormal heat patterns in machines using infrared cameras. Any object with temperature above −273.15 degrees Celsius, absolute zero or 0 kelvin, emits thermal infrared energy undetectable by human eye. Advanced thermal imaging techniques use thermal image scanners to detect and display these infrared wavelengths regardless of visible illumination.
A device known as thermal imager is used in this method to detect radiation emitted from objects, converting it to temperature and creating images of detected temperature distribution known as thermograms. The thermograms are utilized to analyze thermal anomalies in different types of equipment. Abnormal temperature patterns typically precede equipment failures, corroded electrical connections, damaged components, and other conditions requiring attention.
The process relies on fundamental physics of electromagnetic radiation. All objects emit infrared radiation proportional to their absolute temperatures. Hotter objects emit more infrared energy than cooler objects. Thermal imaging cameras contain detector arrays sensitive to infrared wavelengths. These detectors convert infrared radiation into electrical signals which processing circuits transform into visual images.
Color palettes or grayscale representations display temperature variations. Thermal images typically use false color where warmer areas appear as red, orange, or yellow while cooler regions display as blue, green, or purple. These color-coded representations enable rapid identification of temperature anomalies warranting investigation. The human brain processes visual information quickly, making thermal images intuitive diagnostic tools.
