摘要： A force sensing device generates an output signal containing information usable for determining a magnitude and a direction of a force acting on a coupling. The coupling has a hook and a linking element linking the hook to a connection flange. The linking element is linked to the hook and the connection flange by at least two pins. Each pin comprises a torque sensor. The linking element is arranged at an angle with respect to the hook such that independent of the angle of the slope between an imaginary horizontal plane and the longitudinal axis of the connection flange, the linking element does not reach a position, in which the two pins are arranged one above the other in a vertical direction relative to a longitudinal axis of the connection flange.

摘要： A device compensates for the an influence of a magnetic field gradient which may be generated due to a component geometry of a component (1). The device includes at least two magnetic field sensors (17, 18) which are arranged outside of the magnetic balance of the ferromagnetic component (1). The at least two magnetic field sensors (17, 18) each have a differing sensitivity. One of the magnetic field sensors (17, 18) is exposed to the influence of the magnetic field gradient to a greater extent compared to the other magnetic field sensor due to its spatial arrangement relative to the ferromagnetic component (1). The one magnetic field sensor may have a sensitivity lower than the other magnetic field sensor.

Redundant magnetic field sensors, each configured for emitting a signal, may be arranged radially in relation to the component for each of the first and second groups. The signals of the first and the second sensors can be set in relation to each other and in relation to the signals of the redundant first and second sensors.

The magnetoelastic torque sensor system (10) also comprises a secondary sensor unit (16) having at least one magnetic sensitive part (18), in particular a fluxgate, which measures the generated magnetic field or the alternating magnetic field of the magnetoelastic portion (40).
