A pressure sensor 100 may comprise a nylon socket 200, an upper PCB 320, a lower PCB 340, and a hex housing 400. The nylon socket 200 may include co-molded electrical pin conductors 230a, 230b, 230c extending axially from electrical connectors 240a, 240b, 240c defined within a top end of the nylon socket 200 to a bottom end of the nylon socket 200. The upper PCB 320 may have contacts configured to contact the electrical pin conductors 230a, 230b, 230c. The lower PCB 340 may be electrically coupled to the upper PCB 320 and to strain gauges 355 coupled to a diaphragm 360. The hex housing 440 may have an interior axial port 430 extending from a bottom of said hex housing 400 to a counterbore 440 for holding the diaphragm 360, thereby exposing a first side of said diaphragm 360 to the fluid within the axial port 430. |

1. A pressure sensor for measuring pressure of a fluid comprising:
a thermoplastic socket including co-molded electrical pin conductors extending axially from electrical connectors defined within a top end of the socket, said electrical pin conductors extending axially out of a bottom end of the socket; an upper printed circuit board (PCB) having contacts configured to contact ends of the electrical pin conductors; a lower PCB electrically coupled to the upper PCB, said lower PCB also being electrically coupled to strain gauges coupled to a diaphragm; an injection molded first housing including a counterbore for holding said diaphragm, the first housing having an interior axial port extending from a bottom of said first housing to said counterbore, thereby exposing a first side of said diaphragm to an interior of 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 axial port, thereby changing a response of the strain gauges. |
