Magnetoelectric wheel speed sensor introduction
The magnetoelectric wheel speed sensor is designed by the principle of electromagnetic induction. It has the characteristics of simple structure, low cost and no fear of mud. It is widely used in the ABS anti-lock braking system of modern cars.
However, magnetoelectric wheel speed sensors also have some disadvantages:
(1) The frequency response is not high. When the vehicle speed is too high, the frequency response of the sensor can't keep up, and it is easy to generate false signals;
(2) Poor anti-electromagnetic interference capability, especially when the amplitude of the output signal is small.
