Surface temperature monitoring and imaging: Thermography

Infrared photography (or thermography) is a non-destructive technique for monitoring and imaging an object’s surface temperature. A camera captures the infrared spectrumThe spectrum represents the decomposition of electromagnetic radiation according to its different components. of electromagnetic radiations emanating from objects and transforms them into a colour image known as a thermogram.

Infrared thermography is a very powerful technique that allows for remote and contactless analysis of the state of electrical, mechanical and thermal systems while they are operational.

This technique has several applications for buildings:

• Detection of moist insulation in roof systems;
• Detection of moist insulation in walls;
• Detection of heat lossHeat losses are leaks in the insulation of a building. These threaten the efficiency, in addition to being a source of discomfort for the occupants of the building. in wall insulation;
• Locating of leaks (floor heating).

In the electrical field, more specifically in the field of conditional maintenance, this technique has become an invaluable tool, especially for locating hot spots (bad connections, overloads, phase unbalances, faulty contacts, etc.).
