Load cell with a means to compensate for errors due to misalignment

A load cell (1) has a deformable body with upper and lower contact surfaces (3, 4), through which a force is introduced. Support points (5) of the contact surfaces define a line of action (6) of the force. At least one column-shaped portion (7) of the deformable body has a central longitudinal axis...

Zusammenfassung:A load cell (1) has a deformable body with upper and lower contact surfaces (3, 4), through which a force is introduced. Support points (5) of the contact surfaces define a line of action (6) of the force. At least one column-shaped portion (7) of the deformable body has a central longitudinal axis (8) and a circumferential surface whose generating line runs parallel to the central longitudinal axis (8). A first determining means (9) installed on the column-shaped portion converts a mechanical deformation into an electronic signal, and a second determining means (10) installed on the column-shaped portion converts a deviation of the central longitudinal axis (8) from the line of action (6) into a representative signal. Each determining means has at least one strain gauge.
