is a non-contact, non-destructive test method that utilizes a thermal imager to
detect, display and record thermal patterns and temperatures across the surface
of an object. Infrared thermography may be applied to any situation where knowledge
of thermal profiles and temperatures will provide meaningful data about a system,
object or process.
Since infrared radiation
is emitted by all objects based on their temperatures, according to the black
body radiation law, thermography makes it possible to "see" one's environment
with or without visible illumination. The amount of radiation emitted by an object
increases with temperature; therefore thermography allows one to see variations
Thermography is widely used
in industry for predictive maintenance, condition assessment, quality assurance,
and forensic investigations of electrical, mechanical and structural systems.
Other applications include, but are not limited to: law enforcement, firefighting,
search and rescue, and medical and veterinary sciences.
makes Thermography useful?
It is non-contact
-Uses remote sensing
-Keeps the user out of danger
-Does not intrude upon or affect the target at all
2. It is two dimensional
-Comparison between areas of the target is possible
-The image allows for excellent overview of the target
can be visualized for analysis
3. It is real
-Enables very fast scanning of stationary targets
of fast moving targets
-Enables capture of fast changing thermal patterns
is the number one form of measurement used in any process control application.
As we get better at non-contact measurement and customers gain confidence, the
technology will expand. Pressure and flow are also critical measurements as well,
but temperature is far and away number one.
