A sensor system includes a sensor element, a signal processing circuit, and a pseudo-signal correction circuit. The sensor element outputs an electric signal corresponding to an external force. The signal processing circuit converts the electric signal coming from the sensor element into a signal having a certain signal format and then outputs the signal thus converted. The pseudo-signal correction circuit corrects a pseudo-signal outputted by the sensor element. When receiving a test signal, the sensor element performs a self-diagnosis based on the test signal and then outputs the pseudo-signal, which represents a result of the self-diagnosis. The pseudo-signal correction circuit corrects the pseudo-signal based on environment information about an environment where at least one of the sensor element or the signal processing circuit is located.

The invention relates to a centrifuge (10) with a housing (12), in which a rotor (32) for receiving a sample that is to be centrifuged is arranged. The rotor (32) is driven by the drive shaft (22) during operation of the centrifuge (10) and rotates about a rotation axis (30). The rotor (32) has a first, rotor-side transceiver unit, which is excited by an electric field, thus inducing voltage in the first transceiver unit (48). The first transceiver unit (48) is associated with a second, housing-side transceiver unit (62), which is connected to a voltage source. The two transceiver units (48, 62) are connected to a transceiver antenna (52, 64) each, and the transceiver units (48, 62) and the transceiver antennas (62, 64) are in each case arranged on an annular support (46, 60) concentrically with the rotation axis (30).
