1. A flexure body made of a high modulus of elasticity material having first and second opposite parallel outside surfaces and a central opening extending between said surfaces, strain sensing means mounted to the flexure body within said center opening;
at least one printed circuit board carrying bridge circuitry for processing signals from said strain gages on the flexure body, said printed circuit board being mounted to and in parallel with an outside surface of said flexure body; and
a connector structure extending through an outside edge surface of the flexure body for making electrical connections to the printed circuit board, a cover attached to said flexure body and extending over said printed circuit board, wherein the cover is contoured to provide an interior volume to accommodate said printed circuit board and has two concaved clam shell portions, each on and extending over a respective outside surface of said flexure body;
said flexure body further comprising a second printed circuit board having circuit means mounted there on laying parallel to an outside plane surface of said flexure body opposite to the first printed circuit board and within one of the two clam shell portions of said cover.
