How Thermal Imaging Works

All objects above absolute zero (-273C or 0 Kelvin) emit infrared radiation. As an object gets hotter it emits more radiation. Even though visible and infrared light sit side by side in the electromagnetic spectrum, humans cannot see infrared radiation due to the wavelength. A thermal imaging camera can detect this infrared radiation and convert it into visible light. This image is then interpreted and analysed by a qualified thermographer.

The thermal imaging camera detects the different intensities of radiation and assigns a colour. The colour range is set by the user and is normally kept the same throughout the survey.
ERIKS have enough experience to know which palette works best with each type of survey, whether its heat & energy loss through buildings or electrical surveys as part of predictive maintenance & condition monitoring.
We have mentioned experience and qualifications. Both are essential in carrying out a Thermographic survey correctly. ERIKS have invested time and money in fully training all their operatives to a high standard, so they understand and avoid problems that occur whilst carrying out a survey.
Even facing an object (Dependant on temperature, surface type, material), your own body heat effects the amount of infrared radiation emitted from the object. Different materials and different surface finishes on the same material emit radiation at different rates. This is why experience and training are essential.

A key benefit of thermography is that it's non-contact and instant. Faults can be identified quickly, without intruding on the object.
This advantage decreases the risks whilst checking live circuits, hot surfaces and potential hazardous substances / equipment.
