Claim:
1. A pressure sensor for measuring pressure of a fluid comprising: a thermoplastic socket including a plurality of co-molded electrical pin conductors each having a top end and a bottom end, wherein the top ends of the plurality of electrical pin conductors directly contact electrical connectors defined within a top end of the thermoplastic socket for receiving an external electrical cable having suitable reciprocal connectors for plugging into the thermoplastic socket electrical connectors, and said bottom ends of said plurality of electrical pin conductors extending axially out of a bottom end of the thermoplastic socket; an upper printed circuit board (upper PCB) having electrical contacts on a top side of the upper PCB contacting the bottom ends of the electrical pin conductors; a lower printed circuit board (lower PCB) parallel to the upper PCB, the lower PCB connected to the upper PCB by at least one structural member having an upper end directly coupled to a bottom side of the upper PCB and a lower end directly coupled to a top side of the lower PCB, said lower PCB also being electrically coupled directly to the upper PCB and electrically coupled directly to strain gauges coupled to a diaphragm; an injection molded first housing including a diaphragm counterbore for holding said diaphragm, the first housing having an interior axial port extending from a bottom of said first housing to said diaphragm counterbore, thereby exposing a first side of said diaphragm to the interior axial port; and a second housing extending between a bottom portion of the thermoplastic socket and a top portion of the first housing, said second housing including one or both of the upper PCB and lower PCB; wherein said diaphragm is configured to deform in response to fluid pressure contacting it through the interior axial port, thereby changing a response of the strain gauges.
