The human eye is only capable of capturing certain light ranges and is also limited in its ability to capture certain high-speed movements or invisible forces. The human eye is only capable of capturing a very small portion of the greater electromagnetic spectrum. Short, intense wavelengths of light and long, slow wavelengths are outside the capability of the human eye. This is where infrared cameras and thermal imaging can fill in the gaps in human sight. Thermal energy has a much longer wavelength than visible light. It is so long in fact that the human eye can’t even see it. Thermal imaging with infrared cameras expands the “visible” spectrum of the human eye by doing the work an eye cannot. It perceives these longer wavelengths and captures them in a color-coded world that the human eye can understand. Everything in the world with a temperature above that of absolute zero emits some level of heat which can be detected and measured.

What is Thermal Imaging Camera?

Thermal imaging cameras are handheld electronic devices with an integrated visual display, designed for detecting heat energy. A thermal imaging camera uses infrared and thermal imaging technology to convert the image of the temperature distribution of the target object into a visible image through detecting the infrared radiation of the target object and applying signal processing and photoelectric conversion. The thermal imaging camera accurately quantifies the actual detected heat and images of the entire object in real-time in the form of a surface, thus accurately identifying the suspected fault area that is heating. The operator initially judges the fever condition and the fault location through the image color and hotspot tracking display function displayed on the screen of the thermal imaging detector, and strictly analyzes it, thereby embodying high efficiency and high accuracy in confirming the problem.

Why Use Thermal Imaging?

Thermal imaging cameras are the perfect tool for predicting failures because they make the invisible visible. On a thermal image, problems seem to jump right out at you. To keep plants operational at all times many industries have combined their predictive maintenance programs with the most valuable diagnostic tools for industrial applications on the market: thermal imaging cameras.

How thermal imaging cameras work?

Thermal imaging is based upon the science of infrared energy (otherwise known as “heat”), which is emitted from all objects. This energy from an object is also referred to as the “heat signature”, and the quantity of radiation emitted tends to be proportional to the overall heat of the object. In order to do so, the camera must first be fitted with a lens that allows IR frequencies to pass through, focusing them on to a special sensor array which can, in turn, detect and read them. The sensor array is constructed as a grid of pixels, each of which reacts to the infrared wavelengths hitting it by converting them into an electronic signal. Those signals are then sent to a processor within the main body of the camera,

which converts them using algorithms into a colour map of different temperature values. It’s this map which is sent on to be rendered by the display screen. In general, thermal images are grayscale: with white representing heat, black representing colder regions, and various shades of grey indicating gradients of temperatures between the two. However, newer models of thermal imaging cameras actually add colour to the images they produce, in order to help users better identify distinct objects more clearly – using colours such as orange, blue, yellow, red and purple. On a colour thermographic display, warmer components or regions will show up as reds, oranges and yellows, while cooler parts will typically be shown as purples and blues (green usually indicates areas that are roughly at room temperature). Because they measure infrared radiation, and not visible light, thermal cameras are also useful for identifying heat sources in very dark or otherwise obscured environments.

Industry Applications

Automotive Industry

Deconstructing parts of the car can be cumbersome, and thermography offers a non-invasive and non-destructive approach testing which saves time and effort. Tight competition and the chase for better performing, fuel-saving, and lighter automobiles inspires thermography to provide the needed efficiency through doing quality checks on every electrical system, motor assemblies and window heating elements.

Chemical Industry

Industries dealing with hazardous and non-hazardous chemical materials can benefit from infrared cameras helping to detect the resulting heat flow from chemical processes. Thermal imaging makes it easier to capture and measure the temperature distribution with greater accuracy, and also enable the analysis of chemical reactions through the entire process chain.

Electronics and Electrical Industry

Electrical systems and electrical distribution equipment can benefit from the application of infrared cameras and thermography technology. Not only does it prevent humans from having direct contact with these systems and circuits, testing and detection can be conducted without interrupting the flow of power.

Aerospace Industry

Aerospace sets the greatest demands on Infrared camera systems due to the high safety and material requirements presented. Often, high thermal resolutions of 20 mk and/or high frame rate of 100 Hz and more are necessary. Aerospace firms can use thermography to test active heat flows on new composite materials to ensure the next generation of lighter, more fuel-efficient aircraft remain as safe as today’s models.

Metallurgy

The field of metallurgy is entirely dependent upon the right materials heated to the right temperature to ensure a proper outcome. In this case, infrared cameras and thermal imaging offer a number of benefits. First and foremost, infrared thermography in metallurgy can help reduce energy consumption by detecting defects in the insulation of heating chambers, cracks in pans, or issues with similar devices.

Inspections of Mechanical Components

Infrared cameras can safely inspect mechanical systems from various industries to detect issues before they become major problems. Thermal imaging applications as it pertains to mechanical inspections are diverse and include, but are not limited to locate and identify overheating bearings, increased discharge temperatures, and excessive oil temperatures in pumps, compressors, fans, and blowers.
