Thermal imaging cameras translate thermal energy (heat) into visible light to allow us to analyse an object or scene.

They provide us with an image of temperature distribution on a surface or object. They can be used for immediate diagnosis or processed through specialised software for further evaluation, accuracy and report output.

Cameras and Software are loaded with many colour palettes that can be utilised, and the palette you use is generally a matter of personal choice.

Beyond impressing your customer with great images the main objective is to deliver useful data, accurately and clearly.

Below we have a main power switch in a compressor panel. There is a defective connection on ph2 between the busbar and the terminal.

Image 1, a typical thermogram that highlights the anomaly very clearly. In many circumstances, this would be the image i would use for my report.

Image 2, the same image with the Active ROI scaling mode applied to the anomaly area. This allows you to assess the values within the selected ROI only. Temperature data below 52 C is blacked out of the image. The thermal gradient is presented very clearly.

Both images are very relevant for different reasons. As explained the priority is to deliver the data clearly and precisely, however sometimes it’s good to experiment and in some applications we may need to isolate all other temperatures in order to monitor heat distribution.

Thank you.
