Thermal Imaging/ Thermography
Thermal Imaging
Thermal Imaging is a special imaging technique that detects infrared radiation emitted from objects, then maps and translate this information to create a thermal image. IR radiation is invisible to the naked eye! On the other hand, a thermal imaging camera can see and visualize this IR radiation as a thermal image. The thermal image will reflect the heat profile of the object shown by different color pallets indicating the temperature difference. For example, darker colors in the image may indicate colder areas, while brighter colors indicate warmer areas.Thermal imaging is a method that does not rely on light to build the image, thus it is a method of improving visibility of objects in a dark environment making it a great Security & Surveillance tool.
Thermography
Thermography is the art of transforming an infrared image into a radiometric one, which allows temperature values to be read from the image. In order to do this, complex algorithms are incorporated into the thermal imaging camera.Thermography is an accurate, quantifiable, non-contact diagnostic technique used to visualize and quantify changes in surface temperatures based on the Infrared radiation emitted from objects, using a thermal imaging camera. It gives you the power to see problems in a way no other technology can, and allow you to inspect equipment quickly and take accurate temperature measurements from a safe distance.Thermography can be used for any application where heat or temperature is an indicative factor. For instance it can be utilized by any organization in their predictive maintenance programs and regular inspections of assets & equipment, to avoid unexpected shutdowns, ensure efficient / failure-free operation, enhance productivity/ shelf life, and increase the return on investment. In other words, it is a simple and reliable method to evaluate the inspected area performance. Numerous industries worldwide have discovered the advantage of incorporating thermal imaging cameras in their predictive maintenance programs.Thermography can be used, but not limited to, the following applications:
- Electrical/ Mechanical
- Building Inspections & Renewable Energy Resources
- HVAC/ Plumbing Applications
- Solar Inspections
- Medical/ Veterinarian Applications
- Automation Applications
- Academic/ Industrial Research & Development Applications
- Optical Gas Imaging
- Furnace & Boilers Inspections Applications
- Firefighting Applications
- Driver Vision Enhancement.
- Outdoor Activities and Hunting.
Typical Problems that can be discovered using Thermography:
- Water leakage, broken pipes, or moisture in roofs, buildings, walls, etc…
- Poor or missing insulations can also be detected.
- An overheated cable with excess load or lose power connection, defects in high voltage tension cables or transformers will be shown in the thermal image.
Why Thermography?
- Anomalies can be clearly seen on a crisp thermal image.
- Nondestructive.
- No need to shut down the operation; unlike most other methods - thermal cameras can be used to scan the inspected area during normal operation.
- Large areas can be scanned within a short time frame using a thermal camera. For example our lowest thermal camera of 160 x 120 pixels, is equivalent to 19,200 IR Thermometers at the same time.
- You can use a thermal camera to check an overheated cable with excess load or lose power connection, high voltage tension cables, transformers, etc.
- Helps you find faults before real problem occur.
- Measures temperatures.
- Save you valuable time and money.
