The arrangement is configured so that load sensor 50 can be mounted within insert 20' of a root portion of wind turbine rotor blade 5. The sensor comprises a carrier member fixedly connected to the insert so that loads can be transmitted between them, a sensing element being supported by the carrier. The sensing element may be embedded within the carrier, the outer surface of which may comprise a threaded portion, and which carrier may be substantially cylindrical. Preferably, the sensing element is a resistive strain gauge. Insert 20' is configured to receive a fixing bolt 15 for securing the blade to a rotor hub, the insert being further configured to receive the load sensor. The sensor may be permanently mounted within the insert, preferably being bonded to it, or may be removably mounted. Independent claims also define a wind turbine rotor blade and a wind turbine installation employing the load sensor. |
