Thesensor is mounted at a specific gap from a toothed reluctor ring. As the teeth pass by the wheel speed sensor, it changes the magnetic field and produces alternating current or AC voltage. The AC voltage can be seen by a scope as a sine wave. The voltage signal will increase in amplitude with an increase in the speed of the reluctor ring. Typesof Wheel Speed Sensors. Vehicles commonly use two-wheel speed sensors: Magnetic inductive sensor. Hall effect sensor. The magnetic inductive sensor relies on a toothed wheel or a tone ring with magnetic properties. In contrast, the Hall effect sensor uses a magnet and a semiconductor to detect wheel speed. Thepassive speed sensor creates its own AC signal that changes frequency with wheel speed. This signal is only present while the wheel is turning at a rate fast enough to create the AC signal. Vehicles equipped with passive wheel speed sensors do not read at or below 2 mph coming from a dead stop. During a wheel-spin condition, or under a Themerging and processing of the individual wheel speed sensor signals by the control unit provide a single reference speed which is roughly the vehicle speed. A comparison of any individual wheel speed with the reference speed supplies the wheel to road slip (wheel tending to lock) signal. Awheel speed sensor (WSS) or vehicle speed sensor (VSS) is a type of tachometer. It is a sender device used for reading the speed of a vehicle's wheel rotation . It usually consists of a toothed ring and pickup. Theoutput of a speed sensor is highly dependent upon application details such as the size, shape and material of the target. Target types vary significantly, for example spinning gears, turbine blades, a screw embedded in a turning shaft, or a ferrous metal notch on a conveyor belt. Temperaturesensing; Hall Effect Sensors: Bicycle wheels; Gear-teeth; Speedometers; Automotive ignition systems; Generally speaking, vehicle speed sensors can also use other methods to determine wheel speed, such as optical sensors. This makes them suitable for different applications as well; bringing with them their own advantages and Thetwo most important things to know about wheel speed sensors are: 1. What kind of sensor to use 2. Where they can be located. The most common place to find a factory vehicle speed sensor is on the gearbox where you'd usually find a sensor detecting the speed of the output shaft which is directly related to road speed. TheHall-type wheel speed sensor is made using the principle of Hall effect. The Hall-type wheel speed sensor has also been widely used in automobiles, and has the following characteristics: the output signal voltage amplitude value is not affected by the rotation speed; the frequency response is high; Strong anti-electromagnetic wave interference ability. Thereare two types of wheel speed sensors: the active sensor and the passive sensor. Active Wheel Speed Sensors. The wheel speed sensors that are categorised as active sensors have a stark difference from the passive speed sensor. The active wheel speed sensor is said to be "activated" only when supplied with a voltage and generates an Thevehicle speed sensor, also known as a transmission speed sensor or output shaft speed sensor, plays an active role in your car's transmission and cruise control systems. There are also ABS wheel speed sensors (WSS) on a vehicle's wheel hubs (both on the front axle and rear axle). Bytesting the abs sensor / wheel speed sensor you will be able to find out which abs wheel speed sensor is bad and replace only the one that needs to be replaced. It takes very short time to test Apassive sensor creates an AC signal that changes frequency as the wheel changes speed. The ABS control module converts this AC signal to a digital signal for interpretation. It monitors all-wheel speed inputs. 1 What type of sensor is a wheel speed sensor? A wheel speed sensor is a type of vehicle sensor that monitors the rotational speed of each wheel. This information is used by systems such as ABS (Anti-lock Braking System), traction control, and vehicle stability to enhance the safety and performance of the vehicle. 2. Thereare two different types of wheel speed sensors, active and passive. Before you can diagnose a suspected faulty wheel speed sensor, you need to have a good understanding of the type of sensor Kdz7WF.
