Theory Of Infrared Thermography
Infrared Thermography is the science of actually "seeing" heat.
Infrared inspection equipment can detect heat that would normally be
invisible to the human eye and represent it as an image.
In the electromagnetic spectrum, as shown above, infrared radiation
falls in the wavelengths just above that of visible light. This is why
infrared radiation is normally invisible to the naked eye.
Practical Example: If a piece of iron is heated until it glows
red-hot, what is happening?
- When the iron is heated to the point that it is glowing, the
infrared radiation being emitted by the hot iron is so intense that
it crosses into the visible light band and is visible.
- When the heat source is removed and the iron starts too cool, the
infrared radiation emmitted is no longer in the visible band. Of
course, the iron is still hot and is still giving off infrared
radiation as it cools.
- Infrared inspection equipment can see infrared radiation given off
from an object at typical temperature ranges of minus 20 degrees Celsius to as
high as plus 1500 degrees Celsius depending on the equipment used.
These properties allow infrared inspection equipment to see
conditions that would normally go undetected.
WHAT DOES ALL THIS MEAN TO YOU?
Infrared inspection equipment can be used to see ANY thermal difference!!
- see loose and high resistance electrical connections
- see over-loaded, over-heating and open-circuit electrical systems
- see under-lubricated, worn or mis-aligned mechanical components
- locate sub-surface moisture in low slope roofs, identify building heat loss
- AND MUCH, MUCH, MUCH, MUCH MORE!!
