Abstract

A wind power plant comprises an outside ring, an inside ring and roll bodies arranged between an inside jacket of the outside ring and an outside jacket of the inside ring for permitting twisting or rotation of the bearing rings against one another. One of the rings on the jacket comprises an auxiliary sensor at least along a portion of the periphery. The auxiliary sensor together with the primary sensor provided in the other bearing ring are configured in such a way that a twisting or rotational position of the two bearing rings relative to one another can be detected.
