About Thermographic Measurements
Thermographic Testing is a technique based on obtaining an image of the heat distribution over the surface of a test object. At DEKRA, our thermographic measurement experts use a special camera with an infrared sensitive detector and a lens which transmit infrared radiation. The temperature variations in the test subject are revealed as varying shades of grey, with temperature variations as low as 0.1°C able to be detected.
Advanced thermographic measurement methods deployed at DEKRA are used in combination with unmanned aerial vehicles (UAVs), which are unmanned flying tools that carry thermographic sensors able to measure the heat distribution across large surface areas in a fast and efficient way.
Thermographic Testing at DEKRA offers a range of applications and advantages, including:
- Passive thermography - examining the heat distribution in hot specimens such as furnace walls, heat water distribution pipes, insulated structures and electronic circuits
- Active thermography - providing a pulsed source of heat on one side of a specimen and examining the other side for deviations in infrared emission which would correspond to internal in homogeneities or flaws
- Monitoring solar panels for weak cable connections
- Inspecting buildings for heat loss or distribution of warmth
