A clamping device contains a clamp jaw fixed in vertical direction, a clamp jaw moveable in vertical direction and a force transducer for applying a force to the moveable clamp jaw. The moveable clamp jaw is curved. The force transducer preferably comprises a coil and an iron core. In the non-clamping condition of the clamping device, the moveable clamp jaw is loaded with the weight of the iron core. For clamping, a current is applied to the coil that produces a magnetic field that presses the iron core against the moveable clamp jaw.
