    Abstract: In an assembly, for use in transducer type instruments such as accelerometers, having a position sensing movable member including a pick-off element, wherein the movable member is secured to a support member by a flexure or hinge and the support member in turn is cantilevered between two stator members, instrument bias errors resulting from the securing of the non-cantilevered portion of the support member between the stator members can be reduced by aligning the edges of the surfaces of the stators that contact the support member with the centroid of the pick-off element so that the axis of cantilever rotation passes through the centroid of the pick-off area. In transducers having electrical leads on the movable member, the flexure and the support member for electrically connecting the pick-off element to the support member, bias errors can be further reduced by including the area of the electrical leads in calculating the centroid.
