ABSTRACT:
A pressure transducer structure for a pressure transducer of the type comprising a hollow transducer housing, a thin diaphragm provided in one end of the housing, a plurality of semiconductor strain gauges provided on the inside surface of the diaphragm and an intermediate tie point. The intermediate tie point comprises a small curved flexible nonconductive board which is bonded at both ends to the inside surface of the transducer housing in close proximity to the diaphragm. The intermediate tie point further contains a plurality of conductors for electrically coupling very fine wires from the semiconductors at one end and the conductors of a connecting cable at the other end.
