摘要:
A force measurement device includes a flux concentrator with first, second, third, and fourth poles, a magnetic field generating unit generating a magnetic field applied to a test object, and a magnetic field sensing unit with first, second, third, and fourth magnetic field sensors. The flux concentrator is arranged such that each of its poles concentrates the magnetic field. The first, second, third, and fourth poles are arranged such that they form a quadrangle. A first recess is provided such that the first pole is spaced apart from the second and third poles is spaced apart from the fourth pole. A second recess is provided such that the first pole is spaced apart from the third and second poles is spaced apart from the fourth pole. The magnetic field sensors are arranged opposite to each other with the flux concentrator in between and such that the first and third magnetic field sensors both face the first recess and the second and fourth magnetic field sensors both face the second recess. The magnetic field sensing unit provides a signal as an indicator for a force applied to the test object.
