A coil integrated in the sensor housing is energized by a high-frequency alternating current. The emerging electromagnetic field changes when approaching a turbo charger blade and every blade generates a pulse. The controller identifies the speed by considering the number of blades. The DZ140 measures both aluminum and titanium blades and the sensors can be mounted at a relatively large distance from the blade for reliable operation.
