Turbocharger speed sensors
The DZ140 is designed for measuring the revolutions of turbochargers. The system is optimized for modern, thin blades made from aluminum or titanium. Equipped with integrated temperature measurement the sensors can be used both for vehicle and test cell use. Robust Miniature Controller The complete electronics is integrated into an extremely compact aluminum housing. The DZ140 offers a high interference immunity, both in test rig operations and on-vehicle testing. The DZ140 eddy current measuring system is resistant to fuel and oil and robust to high levels of shock and vibration. Combined with maximum operating temperatures of 115°C an integration in the engine compartment is possible. Easy Handling
A tri-colour "status" LED on the controller indicates when the sensor has reached the ideal distance from the turbocharger blades. Furthermore the system is compatible with the previous sensor models. This feature enables reduced installation time.
Measurement of aluminium and titanium blades
The DZ140 is the only measuring system which measures both aluminum and titanium blades. The maximum measurement distance of 2.2mm enables secure and reliable operation. Also both radial and axial measurement installations are possible, enabling greater installation flexibility.
