1. A clamping device for a machine tool for processing workpieces, comprising a clamping body having at least one clamping face for clamping an object to be clamped, in particular a tool or a workpiece, and a sensor arrangement for measurement of a planar setting of a face of the object to be clamped on at the least one clamping face or a possible gap between the face of the object to be clamped and the at least one clamping face, wherein the sensor arrangement has at least one planar setting sensor for the detection of a distance between the at least one planar setting sensor and a portion of the object clamped in the clamping device, projecting laterally in front of the at least one clamping face, and wherein the at least one planar setting sensor is arranged on a portion, which is set back in relation to the at least one clamping face, of the clamping body opposite the portion of the clamped object.
