72233-16 INPUT/OUTPUT TERMINAL ASSEMBLY FOR FLEXURE-TYPE PRESSURE TRANSDUCERS Abstract of the Disclosure An input/output terminal assembly for pressure trans- ducers of the flexure type. The transducer includes a flexure member which senses an applied pressure by means of strain gauges mounted thereon. A known problem with such an arrangement con- cerns the electrical connections to the strain gauges wherein there is conflict between the flexible connections required to accommodate flexure displacement and the rigid connections re- quired to lead away from the gauges since a pressure chamber must be spanned. Previously this conflict has been resolved by bonding an insulative terminal plate proximate the flexure to provide a junction between flexible and rigid conductors. Such an arrange- ment gives rise to problems of construction rigidity and perform- ance if excess bonding resin contacts the flexure. The invention provides a welded terminal plate, which is insulative by virtue of a thick film layer of glass, on which electrical connection may be made to areas of thick film gold.
