Speed Sensor for Turbochargers from Oxford RF Sensors
Oxford RF Sensors Ltd.
December 21, 2006
Oxford RF Sensors Ltd., Weston on the Green, Oxford, U.K., offers a speed sensor for next-generation automotive turbochargers. The system uses a 6 mm dia. probe that can withstand operating temperatures up to 350°C, can measure rotational speeds greater than 400,000 rpm, regardless of blade material, and has a range of >2 mm even where the blade thickness is <0.4 mm. The sensor uses the company's RF technology, operates from a 5 VDC supply, and can be separated from its electronics by up to 3 m. The output, with amplitude independent of speed, is fed directly into the ECU or converted into a pulse/blade or pulse/revolution. The sensor is self-calibrating.
