Load measuring method, load measuring device and load measuring device

摘要

To improve the output signal quality of a load measurement by means of active magnetization, the invention provides a load measuring method for measuring a mechanical load on a test object (14), comprising: a) generating and applying a magnetic field to the test object (14), b) detecting one of the test object ( 14) as a result of a mechanical load on the test object (14) changed magnetic field by means of a first magnetic field detection means (20) to produce a first measurement signal (U1, UAB), c) detecting one of the test object (14) as a result of mechanical stress on the test object (14) changed magnetic field by means of a second magnetic field detection device (22) to generate a second measurement signal (U2, UAT), d) calculating a third measurement signal (UBT) from the first measurement signal (U1, UAB) and the second Measuring signal (U2, UAT), and preferably the steps) forming the difference of one (U2, UAT) of the first and second M Ess signale and the computationally determined third measurement signal (UBT) to produce an output signal, f) determining the voltage applied to the test object (14) mechanical load due to the output signal. Furthermore, a corresponding load measuring device for carrying out the load measuring method is proposed.
