Where can I buy Land Rover ABS sensors?

Professional Land Rover auto parts stores like Cavuri are usually available. However, ABS sensors are generally divided into the following three categories.

1. Linear wheel speed sensor: The linear wheel speed sensor is mainly composed of permanent magnets, polar shafts, induction coils and gear rings. When the ring gear rotates, the tooth top and backlash alternately face the polar axis.

During the rotation of the ring gear, the magnetic flux inside the induction coil alternates to generate an induced electromotive force, which is fed into the electronic control unit of ABS via a cable at the end of the induction coil. When the rotational speed of the ring gear changes, the frequency of the induced electromotive force also changes.

2. Annular wheel speed sensor: The annular wheel speed sensor is mainly composed of permanent magnets, induction coils and gear rings. The permanent magnet is composed of several pairs of magnetic poles, and during the rotation process of the ring gear, the magnetic flux inside the induction coil alternates to produce an induced electromotive force, and this signal is input into the electronic control unit of ABS through the cable at the end of the induction coil.

When the rotational speed of the ring gear changes, the frequency of the induced electromotive force also changes.

3. Hall wheel speed sensor: When the gear is located at the position shown in (a) in the figure, the magnetic field lines passing through the Hall element are scattered, and the magnetic field is relatively weak; When the gear rotates, the density of the magnetic field lines passing through the Hall element changes, which causes a change in the Hall voltage, and the Hall element will output a quasi-sine wave voltage in the millivolt (mV) range. This signal also needs to be converted into a standard impulse voltage by an electronic circuit.

When buying, you should ask clearly about buying and buying the model that suits you.

Hello, generally relatively large auto parts cities are bought and sold.

Scientifically, the amount of electricity passing through any cross-section of a conductor per unit of time is called current intensity, referred to as current. Usually represented by the letter i, its unit is the ampere (André Marie Ampere), from 1775 to 1836, the French physicist and chemist, who made outstanding achievements in the study of electromagnetic effects, and also contributed to mathematics and physics. The SI unit of electric current, the ampere, is named after its surname), abbreviated as "ampere", and the symbol "a", also refers to the directional movement of electric charges in a conductor.

The free charge in the conductor moves in a regular direction under the action of the electric field force to form an electric current.

The electromotive force of the power supply forms a voltage, which then produces an electric field force, under the action of the electric field force, in the electric microampere (a) 1a = 1 000mA = 1 000 000 a, and the electricity stipulates that the direction of the directional flow of positive charge is the direction of the current. The microscopic expression of the current in a metal conductor is i=nesv, n is the number of free electrons per unit volume, e is the amount of charge of the electrons, s is the cross-sectional area of the conductor, and v is the charge velocity.

Nature has many kinds of carriers that carry electric charges, for example, electrons that can be moved in a conductor, ions in an electrolyte, electrons and ions in a plasma, quarks in hadrons. The movement of these carriers forms an electric current.
