Abstract: A retaining bolt for attaching a brake caliper to a support is attached. The retaining bolt is hollow and includes a retaining element which is fixed on one side in a cavity of the retaining bolt, supporting a permanent magnet on a free end. When the retaining bolt is moved due to an external load, the permanent magnet moves in the cavity of the retaining bolt and the modification of the magnetic field thus produced can be measured by a magnetic sensor. The retaining bolt allows the braking power of the disk brake to be measured.

Abstract: The invention relates to a brake caliper of an electromechanical disk brake. According to the invention, in order to measure a widening of a brake caliper when the brake is activated, a rod-shaped holder which is clamped on one side, is arranged in a cavity in a yoke of the brake caliper, perpendicular to a brake disk and a movement of the free end of the holder is measured, for example by means of a magnetic sensor. The widening of the brake caliper is a measurement for the clamping force when the brake disk is actuated.

Abstract: A force sensor, in particular for detecting the forces on a vehicle seat, includes a force measurement cell (1) that has a Hall element. The force measurement cell (1) includes at least one bending bar (2, 3), which from the exertion of force to be detected exeris an influence on the magnetic field in the region of a magnetic-field-sensitive sensor element (6) of the measurement cell (1). The sensing is done with a Hall element (6), held on the at least one bending bar (2, 3), which element, under the force exerted on the bending bar (2, 3), can be deflected in the field of a relatively stationary permanent magnet (4), and a magnetic diagnosis field in the region of the Hall element (6) can be generated whose field lines are located in the plane of the sensor element without influencing the measurement field.

Abstract: A dynamometer (10; 10a; 10b) has a pickup element (11; 11a; 11b), in which a permanent magnet (32) and a sensor (35) are disposed. At least the permanent magnet (32) is surrounded by ferromagnetic material, and the spacing of the permanent magnet (32) from the ferromagnetic material changes upon imposition of a force (F) upon the pickup element (11; 11a; 11b). This change in the spacing causes a change in the field intensity of the permanent magnet (32), which is detected by means of the sensor (35) and converted into a corresponding signal.
