The principle of aluminum infrared pyrometer

Radiation pyrometer or infrared thermometer. These names also apply to those instruments that measure temperature by visible black rays radiated by the measured body.

First, the advantages of infrared thermometer temperature measurement Non-contact temperature measurement by receiving infrared radiation radiated by the measured object has many advantages. In this way, difficult-to-reach or moving objects can be temperature-measured without any problems.
Second, the principle structure of aluminum infrared pyrometer
The infrared radiation energy from the measured object is focused on the detector by the lens through the filter. The detector integrates the radiation density of the measured object, and the infrared light received by the measured object. A current or voltage signal proportional to temperature is generated, and then the temperature signal is linearized, emissivity region and converted into a standard output signal in the connected electrical components. In principle, there are two kinds of portable pyrometers and fixed pyrometers.
