At Heat Seeking Thermal Imaging, we use thermal cameras in a number of applications. From electrical and mechanical surveys to utility substations, thermal cameras help in the discovery of building problems not always visible to the naked eye. We’re often asked, how do thermal cameras work? And what applications should they be used in? This month we’ll explore how thermal cameras work and the applications they should be used in.
How do Thermal Cameras Work?
Thermal or infrared cameras detect the heat given off by an object or person. A thermal camera detects infrared energy, or heat, and converts it into an electrical signal. This signal is then processed by the camera to produce a thermal image on a video monitor. The camera then performs temperature calculations.
Thermal imaging cameras have a lens, just like the visible light cameras we’re all used to. In thermal cameras, the lens focuses waves from the infrared energy present in all objects onto an infrared sensor. Thousands of sensors convert the energy into electrical signals, which create a video image.
These cameras see heat as it radiates off objects. Thermal cameras don’t see through objects, as all objects have their own thermal profile. Thermal cameras see the differences in heat radiating off buildings and objects, which allows a thermographer to identify and evaluate the severity of heat-related problems.
What Applications Can Thermal Cameras Be Used For
- Electrical thermal imaging inspections
- Water intrusion and leaks in floor heating
- Inspections of mechanical equipment
- Inspections of building envelopes
- Commercial building inspections
- Utility substation inspections
Thermal imaging cameras are used in a variety of industries including oil and gas, manufacturing, healthcare, government facilities, large commercial facilities, mining, industrial plants, utilities, agriculture and in residential settings. Thermal cameras can be used to detect problems before they become failure issues. Thermal cameras provide a non-invasive way to analyze a wide range of facility processes and equipment.
