Classification: CPC G | IPC G

Claim 10:
11. A load measuring method for measuring a load at a test object (14) made from a non-ferromagnetic material, comprising:
coating at least one measuring region (11) of the test object (14) with a ferromagnetic metal having a maximum particle size of less than 1 μm,
actively generating a magnetic field in the measuring region, and
capturing a change in the magnetic field parameter on account of the load at the test object (14),
wherein the method is performed using the load measuring arrangement according to claim 1, or a load measuring arrangement obtainable with a production method comprising:
a) providing a test object (14) made from a non-ferromagnetic material or providing a ferromagnetic test object having a non-ferromagnetic electrically conducting separating layer,
b) at least partially coating the test object (14) with a ferromagnetic metal having a maximum particle size of less than 1 μm in order to form a measuring region (11),
c) providing a load measuring apparatus (12) having a magnetic field generating device (18) for generating a magnetic field in the measuring region (11) of the test object (14) and a first and a second magnetic field capturing device (20, 22) for capturing a magnetic field parameter which changes on account of the load in the measuring region (11), and
d) arranging the load measuring apparatus (12) at the measuring region (11).
