Detection device for detecting ice deposits on gas turbine components and gas turbine with such a detection device

摘要

The invention relates to a detection device for detecting ice deposits on gas turbine components (12), wherein the detection device has a film (32) and a printed conductor arrangement (18, 20) for the formation of at least one sensor (16) designed as a capacitive sensor (16). for detecting ice on the gas turbine component (12), and also a method for detecting ice deposits on gas turbine components by means of a capacitive sensor (16), the method comprising the steps of: - measuring at least one characteristic, the size of which in the intermediate space (28) between the associated conductors or electrodes of the capacitive sensor (16) depends; and - performing an evaluation, wherein it is determined in the context of this evaluation depending on the size of the at least one measured characteristic, whether in the space (28) between the associated conductors or electrodes of the capacitive sensor (16) ice or ice deposits are given.
