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.
Likeany other speed sensor, a speed sensor can be an inductive sensor (magnet with a wire coil surrounding it) that produces an AC analog wave, or it can be digital, which produces a square wave. Some wheel speed sensors are designed to detect whether the vehicle is moving forward or backward.
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.

Theyhave two wires: signal and ground. Inside a passive WSS sensor is a permanent magnet core surrounded by copper wire windings. When the teeth on the tone ring rotate past the sensor tip, it changes the magnetic field and induces a current in the sensor windings. The result is a classic sine wave current pattern that changes with wheel speed.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.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.
Asyou drive, a wheel speed sensor record the speed of its respective wheel'and sends the data to the ABS module. Four-wheel ABS always has a sensor for each wheel typically installed directly on the wheel axle or behind the wheel's brake rotor.
Thereare two types of wheel speed sensors: one that uses magnetoresistive principles, and one that uses a magnetic pulse sensor (encoder wheel). A digital output signal is sent to the ABS using active wheel speed sensors, which operate at temperatures between -40°C and +150°C.
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
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.
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

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).
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.
