🥉 What Type Of Sensor Is A Wheel Speed Sensor

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. 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. 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. 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. 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 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 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. 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. 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. .
