The invention relates to a sensor system for determining the temperature and rotational characteristics of a rotating element about an axis of rotation. The sensor system includes: a sensor; temperature sensor, and a temperature sensor arranged to sense a temperature of the rotating element, wherein the temperature sensor has an interrogation unit, an antenna and a sensor element, the interrogation unit is provided for transmitting an electrical transmission signal to the antenna and for receiving an electrical reception signal from the antenna, the antenna is arranged to generate a surface wave in the sensor element based on the transmission signal and to generate a reception signal based on the surface wave reflected in the sensor element, and the reception signal is proportional to thetemperature of the rotating element. The sensor system also includes an inductive position sensor configured to sense information about a rotational characteristic of the rotating element. The sensorsystem further comprises an evaluation unit arranged for generating a first signal having information about the sensed temperature and a second signal having information about the rotational characteristic.
