Configuration of an infrared thermometer - KELLER

IR thermometers are designed in a variety of configurations. These will vary according to optical system, electronics, applied technology, size and type of enclosure. What these instruments have in common is their signal processing chain which begins with an IR signal and ends with an electronic output signal. The process sequence starts with an optical system made up of either lenses or a ...

Infrared thermometer - Wikipedia

A sensor with an adjustable emissivity setting can also be used to calibrate the sensor for a given surface or to measure the emissivity of a surface. When the temperature of a surface is accurately known ( by measuring with a contact thermometer), then the sensor's emissivity setting can be adjusted until the temperature measurement by the IR method matches the measured temperature by the ...

Most common applications of Infrared Thermometers

· Distance: The primary use of infrared thermometers is in measuring the temperature of a subject from a distance. The device is beneficial in situations where it is difficult to reach the object to record the temperature. For example, IR thermometer can come handy when measuring the temperature of air conditioning units that are often out of reach.

Working Principle and Accuracy of Infrared Thermometers

· 2. How does the infrared temperature sensor work? These sensors work by focusing the infrared energy emitted by an object onto one or more photodetectors. These photodetectors convert that energy into an electrical signal, which is proportional to the infrared energy emitted by the object. 3. How accurate are thermal thermometers?
