ABSTRACT:
A measuring arrangement in a roller bearing, which determines the direction of displacement of a displaceable bearing component in relation to a stationary bearing component. Four pressure-dependent resistors (R1, R2, R3, R4) of a bridge circuit are arranged successively in a line, in a measuring area on a bearing component and in a parallel manner in relation to the direction of displacement of the rolling body or the displaceable rolling component. The distance (R1-R2) is exactly the same as the distance (R3-R4) and the distance (R2-R3) is greater than the other distances. The positions of the resistors and the bridge circuit are selected in such a manner that a single output signal with an asymmetrical form is created. The rotational direction is, for example, determined by the evaluation of the deviation of a maximum of the mean position between two adjacent minima.
