    Working Principle

    The sensor uses the longitudinal piezoelectric effect of polymer materials to generate an electric charge when impacted. It converts the vehicle tire’s weight into proportional electrical signals, enabling the detection of wheel load, axle load, and total vehicle weight.


    Two types for CET8311 Piezo Traffic Sensor:


    •Class I (Weigh In Motion, WIM): Used for dynamic weighing applications, with an output consistency of ±7%, suitable for applications requiring high-precision weight data.
    •Class II (Classification): Used for vehicle counting, classification, and speed detection, with an output consistency of ±20%. It is more economical and suitable for high-traffic management applications.
