Termografía

Termografía is a technique that uses infrared imaging to detect heat radiation emitted by objects. This allows for the visualization of temperature differences across surfaces, creating a thermogram. These images reveal patterns of heat that are invisible to the naked eye, providing valuable information for a wide range of applications.

The principle behind termografía is that all objects with a temperature above absolute zero emit infrared radiation. The intensity of this radiation is directly related to the object's temperature. Infrared cameras are equipped with sensors that capture this emitted radiation and convert it into a visible image. Different colors in a thermogram typically represent different temperature ranges, with a color scale or legend indicating the corresponding temperature values.

In industry, termografía is used for predictive maintenance. It can identify overheating components in electrical systems, such as transformers, circuit breakers, and motor windings, which can indicate potential failures. In building diagnostics, it helps detect insulation deficiencies, air leaks, and moisture problems, leading to improved energy efficiency and structural integrity.

Medical termografía, also known as medical infrared imaging, is used to assess blood flow and metabolic activity. It can be employed in the early detection of breast cancer, the assessment of inflammatory conditions, and the monitoring of circulatory disorders. Environmental monitoring also benefits from termografía, aiding in the detection of heat loss from buildings or the identification of pollution sources. Its non-contact nature makes it a safe and effective diagnostic tool across numerous fields.
