1. A sensor arrangement, comprising:

  • a sensor for a mechanical quantity or a thermal quantity of a machine;

    the sensor having an input and an output, the sensor configured and arranged to be attached to the machine;

    a processing circuit having an input end and an output end, the input end of the processing circuit connected to the output of the sensor and providing an output signal through the output end, which is processed for a wireless transmission; and

    a transmitter coupled to the processing circuit and including a modulator for modulating the output signal; and

    a cable, which is coupled to the processing circuit and transmitter;

    the cable having a lead configured and arranged to feed a power supply from an external power supply source to the processing circuit;

    the processing circuit configured to supply the output signal or a signal derived from the output signal, which is processed for wireless transmission, to the lead of the cable for wired transmission through the cable; and

    wherein the output signal is modulated by the modulator of the transmitter according to at least one modulation process from a group comprising amplitude modulation, frequency modulation, and phase modulation.
