COURSE AUTOMOTIVE 28: WHEEL SPEED SENSOR TECHNOLOGY
Wheel speed sensor technology
The way wheel speed signals are recorded has undergone drastic changes in recent years. The mechanical pulse generator ring has been replaced in many motor vehicles by a magnetic encoder. This has also led to totally new ways of diagnosing electrical signals and to new methods for inspecting mechanical components.
With the “wheel speed sensor technology” training system it should be possible to compare tried and trusted techniques in the form of inductive-type and Hall effect sensors directly with magneto-resistive sensors. It is also possible to carry out a mechanical inspection of the pulse generator ring and the magnetic encoder in the training system itself.
