The principles of the hall sensors is what when the gear tooth comes by the sensor,the magnetic field will be changed.Based on detecting this change and the gyro frequency , the sensor will generate a relevant impulse signal,Because of the wide frequency measurement,precise & stable output signal,easy installstion,waterproof and electric-automobile,boats,electric power,weaving,and petroleum field.
