Bestech Australia introduces a new eddy current-based sensor system, the turboSPEED DZ140 designed for fail-safe operation up to 285°C.
Supplied by Bestech Australia, the turboSPEED DZ140 eddy current based sensor system 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 sensor system measures rotational speed of turbochargers in bench and field tests and is suitable for speed measurements of 200 to 400,000 rpm. Measuring just three millimetres in diameter, the sensor provides high immunity to interference in harsh test conditions. The integrated temperature measurement feature records the actual ambient temperature near the sensor.
The turboSPEED DZ140 provides much higher immunity to interference than other eddy current-based revolution counters. Key features of the DZ140 eddy current measuring system also include resistance to oil and dirt; maximum operating temperature of 285°C helping to achieve high precision measurements on a continuous basis; and a well-engineered design enabling easy sensor replacement without further adjustments.
