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. Thewheel speed sensor, also known as the vehicle speed sensor (VSS), is a SENSOR used to measure the steering of the car wheels. Commonly used wheel speed sensors are: magnetoelectric wheel speed sensors and Hall effect wheel speed sensors. 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 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. Thewheel speed sensor is responsible for relaying the wheel speed to the ECU so that it can tell the ABS system how much pressure to safely apply. When the wheel speed sensor is broken or not working as it should, one of the first things that are affected is the ABS system. 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. Awheel-speed sensor consists of a silicon integrated circuit in the sensor head, which is hermetically sealed with overmolded plastic. Bosch wheel-speed sensor circuits use Hall technology, which incorporates the Hall-sensing element, signal amplifier and signal processing all on a single chip. Mostfactory ABS wheel speed sensors will be a two-wire Hall Effect type. These are powered sensors that produce a square wave pulsed output unlike a non-powered variable reluctance sensor that will produce a sine wave output. 42wy5Rg.
