Abstract

There is disclosed a header for a differential pressure transducer. The header has a cylindrical sensor housing section which has a front and a back surface. The front surface has a sensor accommodating recess. There is a plurality of terminal pins extending from the front surface and directed through the housing to extend from said back surface. The pins are arranged in a semi-circular pattern, said sensor housing having a stem aperture and cylindrical wall. A stem housing is positioned in the stem aperture and is brazed thereto. The stem housing has a stem passageway directed through the housing which communicates with a passageway in the cylindrical sensor housing. The cylindrical sensor recess contains a sensing device which receives a first input pressure on one diaphragm surface of the sensing device and a second input pressure on a second surface of the diaphragm to produce a differential output pressure. The header, as indicated, is rugged and simple to use and produce.

Dependent claims

A header for a differential pressure transducer, comprising:

a cylindrical sensor housing section having a front and a back surface, said frontfront surface and directed through said housing to extend from said back surface, said pins arranged in a predetermined pattern, said sensor housing having a stem aperture in said cylindrical wall with said aperture extending from said wall into said housing, said sensor having a passageway communicating at one end with said recess and at other end with said aperture;
a stem housing section positioned in said stem aperture at one end and having a stem passageway directed through said housing section with a first opening at said one end and an opening at said other end to create a fluid path from end to end communicating with said sensor passageway;
and
a sensor having a diaphragm for deflecting upon application of a force thereon, said sensor having pressure responsive elements located on said diaphragm and operative to change value according to the magnitude of an applied pressure, said sensor positioned in said sensor accommodating recess with one surface of said diaphragm aligned with said front surface of said sensor housing and said other surface of said diaphragm communicating with said sensor passageway, said sensor having a plurality of terminals coupled to said elements.
