Turbocharger speed sensors play a vital role in providing overspeed protection. With the further development of its eddy current speed sensor, BorgWarner Turbo & Emissions Systems is presenting its latest innovation to extend the service life of turbochargers. Unlike the predecessor model, the new speed sensor can for the first time be installed not only in commercial vehicle engines but also in passenger cars. The special feature of the new solution is the fact that the sensor is now directly attached to the compressor housing. In addition to providing a price benefit and easier handling, the specialists have also improved the unit's electromagnetic compatibility. This better ensures that the sensor does not cause any electromagnetic interference that might impair the operation of other systems.
