Thermal Imaging Camera: How it works and why it may be necessary
Thermal Imaging Camera model IC- 083
Initially the professional may consider if he really needs an infrared camera. As it is an emerging tool and there are not many references he can doubt about the usefulness of this tool. For this reason, we are going to give a brief description of how it works and several options to use it, in order to take full advantage of this instrument.
How a thermal imaging camera works?
All bodies above absolute zero (-273 °C) emit infrared radiation (heat). In general, the larger the emitted radiation, the higher the temperature of the body. This radiation is invisible to the human eye and its range in the electromagnetic spectrum is between visible light and microwave radiation. Specifically, the wavelength of the infrared is between 0.7 and 1000 microns. Within this wide range, thermal imaging cameras work in a range known as thermal infrared, which is where the most common land surface temperatures are, between 8 and 14 microns, which is approximately between -20 and 350 °C.

The thermography camera has a heat sensor called microbolometer. When it receives infrared radiation it warms and changes its electrical resistance. This change in resistance is measured and compared to a given temperature. A colour is assigned to each temperature which creates a coloured image that will be show on screen. The advantage of these sensors is that they can work at room temperature and does not require refrigeration, so they are cheaper than the sensors for military use.
The detection of these infrared radiations, impossible to see with the naked eye, is particularly advantageous in many situations and can help to prevent many unwanted moments. Non-uniformity of temperature typically indicates a failure or critical point, either by increased blood flow that occurs in an internal injury from an animal or heat leakage which can occur in the critical point of a pipe. Below are listed a few applications:
- Heating of faulty electrical components.
- Friction in engines or electrical machines.
- Imbalance charges.
- Leaks or blockages in pipes.
- Bad electrical connections.
- Prediction of potential fire or damage.
- Overload of electrical circuits.
- Levels in deposits.
- Critical points in pipes.
- Hazardous chemical reactions.
- Energy efficiency.
- Heat leaks.
- Poor insulation.
- Water Leaks.
- Temperature distribution in heating systems.
Medical and Veterinary
- Detection of injuries by increased blood flow.
- Location of living beings.
- Immediate detection of body temperature (fever for influenza A).
- Non-invasive medical analysis.
- Detection of nests or home invaders animals.
Security and other
- Detection of living being in emergency situations (landslide, earthquake...).
- Detection of possible fire outbreaks.
- Detection of stowaways on border crossings.
- Security perimeter.
- Home invaders animals.
- Wildlife viewing and outdoor activities.
As you can see, uses of the instrument are diverse. We have only mentioned some of them that are being used at present. In the future there will be many more as its use is extended. For more information:Specifications of the IC- 083 Thermal Imaging Camera
