Abstract
A sensor device for determining rotational speed of a rotatable object, includes a sensor housing with a sensor segment, a mounting segment and a connector segment, the sensor segment and the connector segment being arranged on opposite sides of the mounting segment, wherein a sensing element is arranged at the sensor tip of the sensor segment, sensor electronics are arranged inside the sensor segment, the sensor electronics including an integrated silicon-on-insulator circuit. The integrated silicon-on-insulator circuit is embedded between flexible polymer substrates. A turbocharger may include such a sensor device. The sensor device is designed to operate continuously at a temperature of at least 200° C.
