What Are Thermographic Cameras?
Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum and produce images of that radiation, called thermograms. 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 in temperature. When viewed by thermographic camera, warm objects stand out well against cooler backgrounds; humans and other heat sources become easily visible against the environment, day or night. As a result, thermography's extensive use can historically be ascribed to the military and security services. This technology is now being extensively used in industry for many different applications and maintenance.
How Can It Help Your Business?
Temperature changes can indicate problems in many everyday applications and a thermal imager makes it quick and easy to visually check surface temperatures.
Often problems can be discovered before the item malfunctions and causes a breakdown which stops production. This allows planned time out with production to be set aside for preventative maintenance, inspection and testing.
Such preventative actions are important because when a critical system fails, it inevitably increases costs, requires the reallocation of workers and material, reduces productivity and, if not corrected, can threaten corporate profitability and, possibly, the wellbeing of employees, customers and/or clients.
What Can It Be Used For?
Thermal images are an easy way to identify apparent temperature differences in many different applications.
