Introduction to thermal imaging
While spot infrared thermometers present only a single temperature at a single spot, Thermal Imaging Cameras give you the whole picture. Thermal imaging is the most effective method for finding problems or potential problems in a variety of applications across many fields.
Thermal imagers allow users to measure temperature in applications where conventional sensors cannot be employed. Specifically, in cases dealing with moving objects (i.e., rollers, moving machinery, or a conveyor belt), or where non-contact measurements are required because of contamination or hazardous reasons (such as high voltage), where distances are too great, or where the temperatures to be measured are too high for thermocouples or other contact sensors. The thermal imagers provide an image, which shows the temperature difference of the object being measured. Hot spots can be seen immediately versus traditional infrared guns, which average the area being measured.
