Infrared Thermography is the technique that uses an infrared imaging and measurement camera to “see” and “measure” invisible infrared energy being emitted from an object.
Thermal, or infrared energy, is energy is not visible because its wavelength is too long for the sensors in our eyes to detect at temperatures below 525 degree Celsius. It is the part of the electromagnetic spectrum that we perceive as heat. Unlike visible light, in the infrared spectrum everything with a temperature above absolute zero emits infrared electromagnetic energy. Even cold objects such as ice cubes emit infrared radiation. The higher the temperature of the object, the greater the infrared radiation emitted. The Infrared camera converts the radiation into an electrical output to form a two dimensional image and allows us to see levels of energy that our eyes cannot discern!
In the industrial/commercial environment, almost everything gets hotter or cooler before it fails, making infrared cameras extremely valuable diagnostic tools with many diverse applications. As industry strives to improve manufacturing efficiencies, manage energy, improve product quality, and enhance worker safety, new applications for infrared cameras continually emerge.
Energy loss, especially form structure, has been highlighted in the latest building codes and faulty refractory or insulation in industry adds to the outlay for energy, increasing consumption and raising the cost of products. There is no better inspection techniques that Infrared Thermography to find these thermal anomalies.
Thermography is used in so many industries for such a variety of application, it is no wonder that most companies have looked into using this technology in some form. The list of applications is limited by imagination but include:
