Beschreibung
Zusammenfassung:	An apparatus is described for measuring the deposition of ice on the rotor blades (5) of a wind turbine (1), having a transmitting and receiving device with parts that are on the rotor blades (5) on the one hand and parts that are arranged in fixed positions and are connected to each other via a wireless transmission link on the other and having an evaluation circuit (9) connected to the transmitting and receiving device. In order to provide advantageous structural conditions, it is proposed that the transmitting and receiving device comprises passive transponders (6) on the rotor blades (5) and at least one stationary reader unit (7) for the transponders (6) and the evaluation circuit (9) has a comparator stage (10) for the minimum transmission output of the reader unit (7) required to read the transponders (6) reliably, with a programmable threshold value for this transmission output in the event of the deposition of ice.
