In the above differential or axle sensor to sense the rotation of the number of laps, usually with Hall, photoelectric two ways to detect signals of automotive sensors which aim odometer count can effectively analyze and judge the car's driving speed and mileage, because the wheel axle and the angular velocity equal to the radius of a known tire, directly calculated by the mileage parameters. Two bearings on the shaft design, greatly reducing the running torque of automotive sensors, reducing friction and enhance the life; motion detection signal changed from the original running gear detector signal; original in-line vertical Transmission to chamfer interface gearbox. Odometer sensor plug is generally in the gearbox, and some open the hood you can see the production of automotive sensors, and some want to operate in the trench. When the sensor is working mechanism of magnetic effect according to Faraday's law of electromagnetic induction, N-turn coil automotive sensors offer motion in a magnetic field, cutting magnetic field lines (or magnetic flux coil where the change), the size of the coil induced electromotive force generated depends on through the rate of change of the magnetic flux of the coil, the linear magnetic sensors linear mobile mobile magnetic sensors by the permanent magnets, coils and other components sensor housing when the housing together with the measured vibration and the vibration frequency of the vibrating body is much larger than the sensor's inherent frequency, since the spring is relatively soft, relatively large mass moving member, the moving member with the vibrating body vibrates together too late (stationary). In this case, the relative velocity between the magnet and the coil vibration velocity close to the vibrating body.
