    Infrared Temperature Sensor Details

    Tips: Advantages of non-contact infrared temperature sensor

    • The non-contact infrared temperature sensor reads moving objects. Since contact temperature sensors do not work well on moving objects, infrared temperature sensors are very suitable for measuring the temperature of tires, brakes and similar equipment;
    • The infrared temperature sensor will not wear out, and there will be no physical friction without contact, so it has a longer service life;
    • Infrared temperature sensors can provide more details, IR sensors can provide more details during measurement than contact devices, just point it at different locations on the object being read;
    • Infrared temperature sensors can be used to detect motion by measuring temperature fluctuations in the field of view.

    The cable is 1.5 meters by default.
    We can customize and lengthen the sensor cable.
    What is the cable length you require?
    Work as expected.
    I bought 10 non-contact infrared temperature sensors from, they are accurate, easy to mount, work well without a problem at all. I'll buy some more if I need. Highly recommend.
