TurboSPEED DZ140 – fail-safe up to 285ºC
Micro-Epsilon: The new eddy current-based sensor system measures the rotational speed of turbochargers in bench and field tests. turboSPEED DZ140 is optimized for thin turbine blades made from aluminum or titanium. The system is thermally stable and very well protected from external interference.
The turboSPEED DZ140 is the third generation of eddy current-based revolution counters for turbochargers. The sensor system is suitable for speed measurements of 200 to 400,000 rpm. The sensor is just three millimetres in diameter, yet it provides the highest immunity to interference in harsh test conditions. The integrated temperature measurement feature records – among other data – the actual ambient temperature near to the sensor. The turboSPEED DZ140 provides much higher immunity to interference than other eddy current-based revolution counters. The DZ 140 eddy-current measuring system is resistant to oil and dirt. The maximum operating temperature of the miniature sensor is 285°C, which is a key advantage compared to optical speed measuring systems, as this helps to achieve high precision measurements on a continuous basis. The well engineered design also enables easy sensor replacement without further adjustments.
