    Wiring of infrared temperature sensor

    Principle of measurement

    Measuring principle of infrared temperature sensor

    • Anything above absolute zero (-273.15℃) can generate infrared light.
    • The infrared temperature receives the infrared dispersion from the object and converts it into a standard signal output through sensors, optical systems and electronic circuits.
    • The infrared temperature sensor can calculate the surface temperature of the object by measuring the infrared intensity emitted by the target without touching the target.
    • The biggest advantage of non-contact infrared temperature sensors is that users can easily measure targets that are difficult to approach or move.

    Measuring distance of infrared temperature sensor

    Optical Resolution: The ratio of the distance from the infrared temperature sensor to the object to the size of the spot being measured (D:S). The larger the ratio, the better the resolution of the instrument and the smaller the measured spot size. The closer the measured object is to black, the higher the measurement accuracy.
