Eddy Current-Based Sensor System is fail-safe up to 285°C.
Press Release Summary:
Optimized for thin turbine blades made from aluminum or titanium, turboSPEED DZ140 measures rotational speed of turbochargers in bench and field tests. This eddy current-based revolution counter is thermally stable and suitable for speed measurements from 200–400,000 rpm. Exhibiting immunity to interference in harsh test conditions, 3 mm dia sensor integrates temperature measurement feature that records, among other data, actual ambient temperature near to sensor.

TurboSPEED DZ140 - Fail-Safe Up to 285°C
The new eddy current-based sensor system measures the rotational speed of turbochargers in bench and field tests. turboSPEED DZ140 is optimised for thin turbine blades made from aluminium or titanium. The system is thermally stable and very well protected from external interference.
The turboSPEED DZ140 is the fourth 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.
