What is thermal imaging ?

When we heard about electrical , energy audit ; for sure we know that there will be someone will be from the team pointing one equipment at every corner of the factory and taking blurry images. Yes my friend that we call thermometer.

It is used in other engineering fields to identify circuits which cause of a fault (like abnormal heating conditions) keeping people and property safe from damage. The thermal image will give a clear picture of the temperature distribution over a surface of a device equipment under inspection.

โ–ช๏ธEmissivity โ€“ The emissivity of the object being measured can affect the accuracy of the temperature reading. Emissivity is the ability of a material to emit thermal radiation and different materials have different emissivity values
โ–ช๏ธReflectivity โ€“ The reflectivity of the object being measured can also affect the accuracy of temperature reading. Highly reflective surfaces such as metal or glass, can reflect infrared radiation.
