1. A sealing system (100) comprising:

  • a seal mounted in a gap between two concentrically mounted, relatively rotatable components, the seal retaining a liquid at an oil side of the seal;

    a sensor for sensing a parameter of interest associated with the liquid and for providing a sensor signal; and

    processing means for processing the sensor signal and determining the parameter of interest,wherein,the sensor is a magneto-elastic resonance (MER) sensor, witha magneto-elastic resonator having a first resonating element which vibrates at a first resonant frequency in response to a time-varying magnetic field, whereinthe resonator produces a sensor signal in the form of a time-varying magnetic flux signal, dependent on the first resonant frequency, andthe processing means is adapted to extract the first resonant frequency from the sensor signal and to determine the parameter of interest based on the first resonant frequency.
