Thermography

Detect hot spots before they cause trouble
Since the dawn of the industrial age, temperature has been used to give an indication of machine condition. Technicians know that abnormal temperatures often indicate a potential problem. Depending on the situation, sometimes just feeling the machine with the back of your hand can help you determine if the temperature is within acceptable limits; of course this method has severe safety limitations especially with rotating machinery and electrical equipment!
To obtain a more quantifiable indication of temperature, direct contact thermometers are often used; a safer method than using the back of your hand, but with some similar safety concerns. Infrared thermometers are often used for hazardous and difficult to access applications.
However, infrared thermometers measure the average temperature of an area and, for accurate measurements, the user often has to be close to the application. Thermography allows you to visualise heat. The application’s infrared radiation is converted by a thermal camera to a visual image.
