摘要: Two spaced-apart outer elements are adapted to be excited by an oscillator. An inner element is disposed therebetween and provides a signal indicative of its spacing relative the other elements. The processed determine this position. arranged on flexure that responsive load form cell wherein from magnitude load. Various arrangements disclosed. preferably parallel plates, having surface area substantially greater than their separation. In embodiment invention, plate bifurcated longitudinally, forming two nominally-coplanar offset effects off center loading with respect output cell.
