Abstract

This invention is concerning a precalibrated multi-component sensor, here called a master balance, intended for determination of applied forces and moments in the calibration of multi-component sensors, here called object balance, normally used for aerodynamically tests in wind tunnels. During the calibration procedure, the object balance is connected in series with the master balance, which in turn is fastened to a frame, here called a calibration rig. Characteristic for this invention is that the master balance is fastened to the calibration rig frame by an attachment joint in a plane perpendicular to the main axis, common to master and object balances, with the attachment joint being lifted up to the same or nearly the same level as the moment center of the object balance.
