Abstract
A method for determining the size of a radial gap between rotating and torsion-proof parts, particularly the parts of a turbomachine is provided. According to the method, an original signal emitted by a transmitter device located on the surface of the rotating part is received in a modified manner by a receiver device disposed on the torsion-proof part and is redirected to an evaluation unit. The evaluation device determines and displays the size of the radial gap from the received signal by determining the parameters of the trajectory of the rotating transmitter device.

A method for determining a radial gap size between a rotating component and a stationary component of a continuous-flow machine, comprising:
- emitting a source signal as a radio wave from a transmitting device arranged on a surface of the rotating component;
- receiving a modified form of the source signal by a receiving device arranged on the stationary component;
- transferring the modified source signal to an evaluation device;
- determining parameters of a path curve of the rotating transmitting device by the evaluation device based on the modified source signal;
- and
- determining the gap size of the radial gap via the evaluation device based on the previously determined parameters of the path curve of the rotating transmitting device.
An apparatus for determining a radial gap between a rotating component and a stationary component of a continuous-flow machine, comprising:
- a transmitting device for emitting a source signal as a radio frequency wave, wherein the transmitting device is arranged on the rotating component;
- a receiving device for receiving a modified form of the source signal, wherein the receiving device is arranged on the stationary component;
- and
- an evaluation device communicatively coupled to the receiving device, and
- wherein the evaluation device is configured for determining parameters of a path curve of the rotating transmitting device based on the modified source signal, and
- wherein the evaluation device is further configured for determining the gap size of the radial gap based on the previously determined parameters of the path curve of the rotating transmitting device.
