Load measuring method, load measuring device, and load measuring mechanism

摘要

A load measurement method for measuring the mechanical load of the test object 14 to improve the output signal quality of the load measurement by active magnetization includes the following. a) Generate a magnetic field and apply it to the test object 14. b) Detecting with the first magnetic field detection device 20 the changed magnetic field in the test object 14 as a result of the mechanical loading on the test object 14 and generating the first measurement signals U1, UAB. c) The second magnetic field detection device 2 detects the changed magnetic field in the test object 14) as a result of a mechanical load on the test object 14 and produces a second measurement signal U1, UAB. d) The third measurement signal UBT is determined by calculation from the first measurement signals U1, UAB and the second measurement signals U2, UAT. Preferably it also includes: e) Forming the difference between one of the first and second measurement signals U2, UAT and the third measurement signal UBT determined by calculation to produce an output signal. f) Determine the mechanical load applied to the test object 14 based on the output signal. The invention also provides a corresponding load measuring device for performing the load measuring method.
