    Abstract: A transducer assembly includes first and second stators which are axially aligned with, and bear upon opposite sides of a proof mass. The stators and proof mass are clamped together by means of a sleeve having a side portion with spaced apart upper and lower flanges extending therefrom. The flanges bear against receiving surfaces on the stators with the sleeve under elastic deformation such that a compression force tending to reduce the spacing between the flanges is transmitted to the stators and proof mass as a controlled compressive axial preload.

    Abstract: A transducer assembly includes first and second stators which are axially aligned with, and bear upon opposite sides of a proof mass. The stators and proof mass are clamped together by means of a sleeve having a side portion with upper and lower flanges projecting therefrom. An inner sleeve element, formed from a material having a different coefficient of thermal expansion than the side portion, is disposed between the flanges. The temperature of the sleeve is controlled such that the inner sleeve element produces a tensile stress on said flanges, increasing the spacing therebetween. The flanges are then joined to the stators. Thereafter, the temperature of the sleeve is controlled such that the tensile stress produced by the inner sleeve element on the flanges is reduced producing a compression force tending to reduce the flange spacing. This compression force is transmitted to the stators and proof mass as a controlled compressive axial preload.

    Abstract: FORCE TRANSDUCER FLEXURE WITH CONDUCTORS ON SURFACES IN THE NEUTRAL BENDING PLANE A flexure in a force transducer, as an inertial guidance accelerometer, for securing a force sensitive element to a mounting base includes one or more flexure sections having one or more recessed surfaces which are substantially coincident with the neutral bending plane of the flexure. Electrically conductive coating on the recessed surfaces provide electrical connections to components located on the force sensitive element. The conductive coatings on or near the neutral bending plane of the flexure sections minimizes bending moments caused by stresses set up between the conductive coatings and the flexure which may in turn lead to bias errors. At the same time, the flexure configuration provides for the desired strength and spring rate for the force sensitive element.
