introduction：The increment of displacement per unit time is the velocity。Velocity includes linear velocity and angular velocity，Corresponding to the wired speed sensor and angular speed sensor，We call them all speed sensors。The figure above shows the schematic diagram of the magnetoelectric speed sensor，A bridge circuit consisting of two reluctance elements and two resistors，The differential output signal is sent directly after the detection signal is taken outDCAmplification by amplifier。The working principle is when the rotating mechanism of the sensor rotates under the action of external driving，It spins the permanent magnet，The magnetic field passing through the Hall element will produce periodic changes，Causes the output voltage of Hall element to change，A stable pulse voltage signal is formed through subsequent circuit processing，As the output signal of the speed sensor。
