Abstract (en)
[origin: WO2020157278A1] The invention relates to an arrangement (100) for measuring a mechanical load on a test object, with the detection of changes in the magnetic field, said arrangement comprising a test object (14), which extends in a longitudinal direction L, and at least one sensor element (18) comprising a magnetic field generation device (20) for generating a magnetic field in the test object (14) and a magnetic field detection device (22) for measuring a change in the magnetic field in the test object (14). The sensor element (18) is arranged on a measurement surface (15) of the test object (14), at least one directional component of said measurement surface extending radially and/or transversely to the longitudinal direction L of the test object (14). A magnetic field is generated in the test object (14) and a change in the magnetic field in the test object (14) is measured on the measurement surface (15). The load measured is, in particular, a torque.
