Device for gauging geometry on a workpiece and method for gauging geometry on a workpiece

摘要

A device for the geometric measurement on a workpiece, comprising a housing with a flow channel, in which a reference nozzle for the through flow with a measuring fluid is arranged, a first pressure measuring device for measuring a first measuring fluid pressure upstream from the reference nozzle, and a second pressure measuring device for measuring a second measuring fluid pressure downstream of the reference nozzle, so that they are particularly precise geometry measurements is made possible, it is proposed that the device is a difference pressure measuring device for measuring a reference nozzle by means of the applied measuring difference pressure fluid comprises.
