Abstract: Sensing and electrical-signal characterization of fluid pressures is effected by a miniature precision transducer manufacturable at low cost from a combination of a pair of sub-assemblies, one of which consists of a single-piece metal transducer element having a flanged body with a blind-hole port leading from a mechanical pressure fitting to the inner side of a transverse thin diaphragm which forms the blunt flat end of the body except for a bonded covering of both the machined outer side of the diaphragm and its coplanar annular rigid rim by a foil-type rosette strain gage bridge array and its layer of supporting insulation.
