For measuring basis weight of a moving web in the cross direction scanner of a paper-making machine, an encapsulated nuclear source of Promethium 147 is used because of its wide area of emission. To conserve space it is mounted on a vertical axis 30 the source moves in a horizontal plane parallel to the moving web from a stowed position where the source is shielded to an active position where the source emits through an aperture, through the moving web, and to a detector. The x-y array planar type detector uses four detector segments symmetrically arranged around a center and compensates for belt direction misalignment (the belt driving the cross direction scanners) by mathematically manipulating the electrical signals from each detector to eliminate the error term.
