Abstract: A linkage for use in moment balancing measuring apparatus of the pneumatic type includes first and second pivotally mounted levers, the second lever being adapted to be acted upon by a measuring force and the first lever being adapted to be acted upon by a pneumatic force for balancing the linkage. According to the invention, apparatus are provided for adjustably varying the leverage ratio of the linkage, i.e., the ratio of the pneumatic force to the measuring force according to the particular application to which the linkage is put. The leverage ratio adjusting apparatus includes a rod-like member having one end rotatably attached to one of the levers and first locking means for selectively securing the rod-like member in a particular position corresponding to the particular application to which the linkage is put.
