The Led motorcycle speedometer installed on the motorcycle can reliably measure the real-time speed of the vehicle. Many speedometers today are electronic, and their design is derived from early eddy current models. Traditional mechanical speedometers use gears and wires to determine speed, while most modern vehicles use speed sensors in electronic speedometers.
The electronic speedometer measures the vehicle speed with the help of the speedometer sensor. In the design derived from the earlier eddy current model, the rotation sensor installed in the gearbox emits a series of electronic pulses whose frequency corresponds to the speed of the driveshaft and therefore to the speed of the wheels. The sensor is usually a set of one or more magnets mounted on the output shaft or the differential crown wheel or a toothed metal disk located between the magnet and the magnetic field sensor. When the part involved rotates, the magnet or tooth passes under the sensor, generating a pulse in the sensor at a time because they affect the magnetic field strength to be measured. In addition, in the latest designs, some manufacturers rely on pulses from ABS wheel sensors. The computer converts the pulses into speed and then displays the speed on an electronically controlled analog pointer or digital display. Electronic speedometers are more reliable and more compact than mechanical speedometers. Motion sensors can keep any distance from the display that shows your speed, so they are suitable for any type of vehicle from bicycles to large commercial vehicles.
To illustrate the calibration of a motorcycle electronic odometer, we take the VDO odometer with an LCD display as an example. The process is a relatively simple process and can be done in three ways: automatic calibration, manual calibration or pulse per mile calibration and fine-tuning. You can use these calibration functions by pressing the buttons on the front of the speedometer and holding them while turning on the ignition. When you see the method you want to use, release the button and the function will be enabled. Among the three methods, automatic calibration is the simplest. But this method has its own limitations. It can only be used successfully on roads or on dynamometers marking the actual designated one-mile distance. If you know the exact calibration value of the vehicle and the type of sensor used (pulses per mile or kilometers per mile), you can choose the second method to manually calibrate the speedometer. Using the third method, you can use the speed test equipment and the "AdJuSt" function on the LCD reader to fine-tune the calibration of the analog display of the speedometer.
