Abstract
The invention relates to a force and angle sensor for measuring the angle of rotation of a shaft () and a force exerted on a torsion rod (), which interconnects two shaft parts () of the shaft (). In a housing (), through which the shaft () runs, are arranged a main circuit board () arranged non-rotatably in relation to the housing () and which has a central opening (), through which the shaft () runs, a first circuit board () for measuring the angle of rotation arranged non-rotatably on a first shaft part () on one side of the main circuit board (), said first circuit board having a central opening () through which the first shaft part () runs, and a second circuit board () for measuring the force connected non-rotatably to the other shaft part () on the other side of the main circuit board (), said second circuit board having a central opening () through which the other shaft part () runs. The planes of the main circuit board (), of the first circuit board () and of the second circuit board () each run perpendicularly to the longitudinal axis of the shaft (). Mutually opposing electrodes for measuring the angle of rotation and/or the force and for the capacitive measurement of the twist between the first circuit board () and the main circuit board () and/or the twist between the second circuit board () and the first circuit board () are arranged on the surfaces of the main circuit board () and of the first circuit board (), said surfaces being turned towards one another, and also on the surfaces of the main circuit board () and of the second circuit board, said surfaces being turned towards one another.
