Principle of household infrared temperature measuring gun

Principle of household infrared temperature measuring gun
The infrared temperature measuring gun is composed of optical system, photoelectric detector, signal amplifier, signal processing, display output, etc. The optical system converges its view
The direction of infrared radiation energy in the field and the size of the field of view are determined by the optical parts of the thermometer and its orientation. When measuring with infrared radiation thermometer
The infrared radiation of the target in its band range shall be measured first, and then the temperature of the target shall be calculated by the thermometer.
The monochromatic thermometer gun is proportional to the radiation in the band, and the two-color thermometer is proportional to the radiation in the two bands. Infrared energy focused on photoelectricity
The detector is converted into corresponding electrical signal. The signal passes through the amplifier and signal processing circuit, and is converted into the temperature value of the measured policy after rate correction and ambient temperature compensation according to the built-in algorithm and policy of the instrument.
