Abstract

A pressure sensor comprising a first housing piece defining a lumen therethrough and an opening to said lumen to provide communication between said lumen and a sensing element, said first housing piece having a first surface surrounding said opening, a second housing piece shaped for mating with said first housing piece and providing, with said first housing piece, a region for containing a sensing element in position to communicate with said lumen via said opening, said second housing piece having a second surface that surrounds said region and faces and conforms to the shape of said first surface, said second housing piece including an end of an electrical wire and wire contacts that are electrically connected to said wire, have portions at or near said second surface, and are spaced from each other, a sensing element in said region in communication with said flow path via said opening, said sensing element including sensor contacts aligned with respective wire contacts, and an elastomeric sheet providing a seal between said first and second surfaces and having a hole therethrough aligned with said opening and plural separate conductors on its surface facing said second surface to make electrical contact between respective said wire contacts and sensor contacts. Also disclosed are insulation displacement blades to provide electrical connection between a sensing element and a wire, and a compressed elastomeric displacement sealing ring filled with gel and providing a communication path between the opening and the sensing element.
