1. A method for monitoring a machine, the method comprising:

  • providing an electrical signal for transmission to and into a component of the machine;

    monitoring a capacitance associated with the electrical signal in the component;

    determining an increase in the monitored capacitance as the component of the machine moves towards another component of the machine;

    determining that the increase in the monitored capacitance exceeds a threshold value;

    detecting a potential rub condition for the component of the machine based at least in part on the determination that the increase in the monitored capacitance exceeds the threshold value; and

    determining a severity associated with the potential rub condition based at least in part on a length of time for which the increase in the monitored capacitance exceeds the threshold value.
