Sensor arrangement comprising an angle sensor and rolling bearing arrangement comprising sensor arrangement

Abstract

A sensor arrangement comprising an angle sensor for measuring torsion is disclosed. The angle sensor is designed for carrying out a measurement via n poles, where n≥1, and primarily comprises a sensor ring which at least partially surrounds a rotational axis, and a material measure which is rotatable relative to this sensor ring. One transmitting coil and multiple receiver coils are situated on the sensor ring. A magnetic circuit is formed between the transmitting coil and the receiver coils, which magnetic circuit comprises the material measure and a pot core including two limbs. In this case, the material measure forms a variable reluctance in the magnetic circuit. At least one of the two limbs of the pot core is segmented in such a way that the limb comprises ring segments. Each of the receiver coils surrounds at least one of the ring segments. Each of the ring segments forms a circular arc having a mean radius. The ring segments may be provided in pairs. The mean radii of the two ring segments of the individual pairs have an angle (β) relative to each other of (60°/n+i·360°/n), wherein i is a whole number. The disclosure further relates to a rolling bearing arrangement.
