ABSTRACT:
A strain gauge balance consisting of an outer longitudinal shell and a monopiece inner center core; the outer shell having a open end and a closed end with a frustoconical bore extending towards the closed end, and the inner core having frusto conical shaped ends, one end being sized to fit within the frusto conical core and the other end being sized to fit into a sting; four radially extending, equally spaced, webs formed within the core and at each end of the core inboard of the frusto conical ends, and a central region of two longitudinally separated, semicircular cross-section parts each being formed within the part, with tensioning rings, one disposed diagonally to the other, and a number of strain gauges secured to the webs and the rings to determine induced strain in 6 degrees of freedom.
