Patent ID: 7690273

Claim:
A force-measuring device with a measuring unit, and further with a reference unit serving to deliver, a reference current (I REF ) by means of which the force (F MO ) of a measurement object which is to be determined can be measured by the measuring unit, wherein the reference unit is a force-measuring device which is loaded with a reference mass and which in accordance with the principle of electromagnetic force compensation generates the reference current (I REF ) that can be controlled by means of a measuring- and regulating device, so that in a first reference coil which is held by a reference lever the reference current (I REF ) generates a magnetic field which interacts with the magnetic field of a reference magnet in such a way that a magnetic force is brought to bear on the reference lever, wherein the force (F REF ) of the reference mass which is likewise acting on the reference lever can be compensated by said magnetic force.
