Odometer Sensor           

     The odometer sensor is based on the principle of measuring speed to measure the speed of wheels. According to the diameter of wheels, each speed cycle is used to circle the wheels, and the mileage of the wheels is calculated by the number of cycles that are accumulated by wheels.           
      The sensor has the national invention patent, and has the characteristics of high reliability, heat resistance, wear resistance and low cost. The double pulse is a speed measuring cycle, and the internal Holzer switch is used to measure the accuracy accurately.
