Describe how thermography is used for predictive maintenance.

Thermography, also known as infrared thermography, is used for predictive maintenance by detecting abnormal temperature patterns in equipment, which can indicate potential problems before they lead to failures. All objects emit infrared radiation, and the amount of radiation emitted depends on the object's temperature and emissivity. A thermographic camera captures this infrared radiation and converts it into a thermal image, which shows the temperature distribution across the surface of the object. In predictive maintenance, thermography is used to scan equipment such as e....
