What is Thermal Imaging and how important is it in temperature measurement?
In temperature measurement it is crucial that the temperature readings are correct to ensure the efficiency, safety, and process of your operations flow correctly. The creation of thermal imaging technology made it simpler to obtain non-contact accurate readings especially in complex systems.
Thermal imaging cameras detect temperature by recognising and capturing different levels of infrared light. The light is invisible to the naked eye but can be felt as heat if the intensity is high enough. All objects emit some kind of infrared radiation, and it’s one of the ways that heat is transferred. The hotter an object is, the more infrared radiations emits which can be convert into an image that we can then see with our own eyes.
A key benefit of thermal imaging technology is that it enables you to quickly identify areas of concern, the cameras can pick up energy leaks, machinery overheating, faulty electrical equipment, fire survival faults once detected you are able to prevent problems before they become bigger issues. Thermal imaging cameras can also be a tool used for predictive regular maintenance routines.
There are a wide range of thermal imaging cameras available, from compact and portable devices to larger complex industrial application units. There is also a wide range of accessories and software options to assist the capabilities of thermal imaging cameras, which makes it easier to receive the information needed to analyse results effectively.
Although all thermal imaging technologies have advantages there are also limitations to the technologies, certain environments such as high levels of reflective surfaces, high ambient light, and some surfaces do not emit enough infrared radiation which can obscure the reading making in unreadable.
Where did thermal imaging camera originate?
It is unclear the origins of thermal imaging. There have been numerous accounts of thermal imaging by other names from the 1800’s but no confirmed inventor. The thermal imaging cameras used today are based on technology that was originally developed for the military. In 1929, Hungarian physicist Kálmán Tihanyi invented the infrared-sensitive (night vision) electronic television camera for anti-aircraft defence in Britain. The first American thermographic cameras developed were infrared line scanners. Thermal imaging in its present form was originally developed for military use during the Korean War
Where do we use thermal imaging?
Thermal imaging cameras have migrated into other fields and have found many uses.








Science and research are undoubtedly sectors that draw significant benefits from using thermal imagers, for accurate and precise visualisations of heat patterns such as dark side of the moon.
Other applications which use a thermal imaging camera include heating, ventilation and air conditioning installations, mould detection, quality assurance in processes such as glass manufacturing and many more.
Money saving is something you wouldn’t necessarily expect from a thermal imaging device, but when you think about everything it can do, it makes sense. After the upfront cost of purchasing the device, they can undoubtedly save your business or home thousands of dollars or more in potential maintenance and repair costs that might incur if faults, leaks, or weaknesses were not identified earlier.
However, it’s important to recognise that while thermal imaging has all these applications, it’s often best to use additional instruments or tools when appropriate to confirm what you’re seeing. Additionally, it’s worth noting that thermal imaging cameras are unable to see through walls and objects, but rather, they only pick up what’s reflected off them.
Choosing and purchasing a high-quality thermal imaging
It’s crucial to use a high-quality product to ensure that you detect and record accurate measurements. A big difference between different types of thermal imagers are the resolution and clarity of the images they provide.
