MICRO-EPSILON's turboSPEED DZ135 Speed Sensor System for counting turbocharger revolutions is optimized for modern, thin blades made of aluminum or titanium on the turbine wheel. Thereby, the sensor measures on the vanes in the complete speed range. Different sensor models with only 3 mm diameter allow simple mounting on the turbocharger. The sensor adjustment and set up are made significantly easier due to a status LED. The generous length of the sensor cable (up to 25 m) and the completely closed controller meet further practical requirements.
