The invention relates to a turbomachine having a rotor (10) comprising rotor blades (12), having a rotor housing (16) which surrounds at least sections of the rotor (10) or the rotor blade (12) so as to form a rotor gap (d), and having a gap-measuring system (18) which is coupled to a capacitive sensor device (20) having an electrode and a counterelectrode for determining measured capacitance values (C) which characterize the rotor gap (d), wherein the rotor (10) or the rotor blades (12) is/are connected as the electrode of the sensor device (20), wherein at least part (22) of the rotor housing (16) is connected as the counterelectrode. The invention also relates to a gap-measuring system (18) and to a method for determining a rotor gap (d) between a rotor (10) comprising rotor blades (12) and a rotor housing (16) of a turbomachine, which rotor housing surrounds at least sections of the rotor (10) or the rotor blades (12). |
