Thermal Imaging works by detecting infrared radiation. All objects above absolute zero (-273°C 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.
