Tips: Working principle of non-contact infrared temperature sensor

Any object radiates infrared energy outward, and the intensity of the radiation varies with temperature. An infrared temperature sensor is an optoelectronic sensor that receives infrared radiation and converts it into an electrical signal, which is amplified, linearized, and processed by electronic circuits to display or output temperature. The size of the measured target and the optical properties of the infrared thermometer determine the distance between the measured target and the measuring head. In order to avoid measurement errors, the measured target should fill the field of view of the detector head as much as possible. Therefore, the measured point should always be kept smaller than the measured object or at least the same size as the measured target.
