The invention relates to a load measurement device () for accurately measuring a load in a test object () such as, in particular, a chassis component, comprising a magnetic field generating device (), a first magnetic field detecting device (), a second magnetic field detecting device (), and a measurement environment parameter acquisition device () for acquiring at least one measurement environment parameter in the test object (), wherein an evaluation device () is configured to generate a measurement signal obtained on the basis of outputs of the first and second magnetic field detection devices () in dependence on the at least one measurement environment parameter detected by the measurement environment parameter acquisition device ().

Device and arrangement for measuring load on a test object, in particular a chassis component

To improve the output signal quality of a load measurement by means of active magnetization, the invention provides a load measurement method for measuring a mechanical load on a test object (), comprising: a) generating and applying a magnetic field to the test object (); b) detecting a magnetic field changed by the test object () as a result of a mechanical load on the test object () by means of a first magnetic field detection device () to generate a first measurement signal (U, UAB), c) detecting a magnetic field changed by the test object () as a result of a mechanical load on the test object () by means of a second magnetic field detection device () to generate a second measurement signal (U, UAB), d) computationally determining a third measurement signal (UBT) from the first measurement signal (U, UAB) and the second measurement signal (U, UAT), and preferably comprising the steps of e) forming a difference from one (U, UAT) of the first and the second measurement signals and the computationally determined third measurement signal (UBT) to produce an output signal, f) determining the mechanical load applied to the test object () based on the output signal. The invention also provides a corresponding load measurement device for carrying out the load measurement method.
