The invention relates to a sensor arrangement with an angle sensor for measuring rotations. The angle sensor is designed to take measurements via n poles, where n ≥ 1, and comprises a sensor ring which at least partly surrounds a rotational axis (04) and a material measure (14) which can be rotated relative to the sensor ring. A transmitting coil and multiple receiving coils are arranged on the sensor ring, and a magnetic circuit is formed between the transmitting coil and the receiving coils, said magnetic circuit comprising the material measure (14) and a shell core (17) with two limbs (18, 19). The material measure (14) forms a variable reluctance in the magnetic circuit. At least one of the two limbs (18) of the shell core (17) is segmented such that the limb comprises ring segments (38). Each of the receiving coils surrounds at least one of the ring segments (38), and each of the ring segments (38) forms a circular arc with a mean radius (51). According to the invention, the ring segments (38) are provided in pairs (43, 44, 46, 47). The mean radii (51) of the two ring segments (38) of the individual pairs (43, 44, 46, 47) form an angle (β) relative to each other of (60°/n+i·360°/n), wherein i is a whole number. The invention further relates to a rolling bearing arrangement. |
