Abstract

The invention relates to a load gauge comprising a generator-sensor assembly. Said assembly comprises a generator unit that generates a magnetic field and a sensor unit that is sensitive to magnetic fields, said generator unit and sensor unit being displaceable by a force in relation to one another. According to the invention, the generator unit comprises at least one permanent magnet and a second permanent magnet, each with a geometric cross-section that remains essentially constant in a longitudinal direction. The first permanent magnet and the second permanent magnet are situated at an angle to one another.
