About Infrared Thermography
Thermography is the use of an infrared imaging and
measurement camera to "see" and "measure" thermal
energy emitted from an object. Thermal, or infrared
energy, is light that is not visible because its
wavelength is too long to be detected by the human eye;
it's the part of the electromagnetic spectrum that we
perceive as heat. Unlike visible light, in the infrared
world, everything with a temperature above absolute
zero emits heat. Even very cold objects, like ice
cubes, emit infrared. The higher the object's
temperature, the greater the IR radiation emitted.
Infrared allows us to see what our eyes cannot.
Infrared thermography cameras produce images of
invisible infrared or "heat" radiation and provide
precise non-contact temperature measurement
capabilities. Nearly everything gets hot before it
fails, making infrared cameras extremely
cost-effective, valuable diagnostic tools in many
diverse applications. And as industry strives to
improve manufacturing efficiencies, manage energy,
improve product quality, and enhance worker safety, new
applications for infrared cameras continually emerge.
With thermal imaging, power lines maintenance
technicians locate overheating joints and parts, a
telltale sign of their failure, to eliminate potential
hazards. Where thermal insulation becomes faulty,
building construction technicians can see heat leaks to
improve the efficiencies of cooling or heating
air-conditioning.
Advantages of Thermography
You get a visual picture so that you can compare
temperatures over a large area.
It is real time capable of catching moving targets.
It is capable of locating deteriorating components
prior to failure.
Can measurement in areas inaccessible or hazardous for
other methods.
