Thermal Imaging vs Infrared Thermometer | Types of Thermal Imagers

A thermal imager is a non-contact temperature measurement device. Thermal Imagers detect the infrared energy emitted, transmitted or reflected by all materials - at temperatures above absolute zero, (0°Kelvin) - and converts the energy factor into a temperature reading or thermogram. A thermogram is the thermal image displayed by the camera of the object which is emitting, transmitting or reflecting the infrared energy. 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.
