What is infrared thermography?
Infrared thermography is a non-invasive technique for detecting heat in an area. It's widely used for testing and inspecting materials, equipment, and other items. The infrared beam scans for temperature differences, measuring radiation emitted from objects in the area. It is used further for comparing it with a baseline.
How does Infrared thermography work?
Typically, Thermography Testing in Toronto uses either a sensor and a lens or two sensors for on-site testing. The lens is referred to as a "thermographic camera." The camera collects the infrared beam and transfers it to a detector, which produces an electrical charge proportional to the temperature of the object under test.
The camera is typically located on a tripod, while the sensors are inserted into flexible plastic sleeves that fit around the object being tested. Once the object has been wrapped in a highly reflective layer of aluminium foil (air gauge), this process can yield information about its temperature distribution and hot spots.
What areas can it be used in?
Infrared thermography can be used to help detect faults in boilers, air conditioning systems, cooling towers, solar panels, electrical circuits or other devices. It is also helping engineers and scientists to explore space.
Infrared thermometers can be used to test other objects too. These include pipes and engine parts for automobiles. They are a cheap and accurate way of uncovering faults that may otherwise go unnoticed.
Thermography testing is also used to check the health of buildings and other structures because it can reveal more than just temperature. It gives insight into how well a building is insulated and how well air flows through it.
Some infrared thermographers use thermography to detect leaks in the cooling system of a building; others use infrared thermography as part of their analysis of an area's structural integrity, looking for signs that an earthquake has damaged a building. It can also be used in security applications.
This is a simple yet informative process. There are no moving parts in the system, nor any contact made with the object being tested. The only direct effect is that the infrared beam has to travel through the air, which limits the precision of measurements. However, infrared thermography is considered an effective and reliable way of evaluating the thermal behavior of electrical or mechanical components in a structure.
To conclude
Infrared thermography is a tool that can be used to test any type of material, electrical or mechanical components. It is also a method for many different professions to obtain more knowledge about the objects they are testing, and when investigating an area it can give insight into the temperature distribution and hot spots.
