Abstract

The invention includes differential pressure transducer assembly systems and methods in which headers are configured with header pins that extend perpendicular with respect to an axis of the assembly and through header sidewalls, enabling a compact configuration, ease of assembly, enhanced reliability and/or redundancy. Channels and ports defined in a housing portion of the assembly are configured to enable the use of substantially straight tubing sections for routing main and/or reference pressures to one or more differential sensing elements mounted on the headers. Two or more headers with associated sensing elements can be stacked to provide redundant differential pressure sensing.

Claims20

Dependent claims

A differential pressure transducer assembly, comprising:

a housing characterized by a front side and a back side in axial alignment along an axis extending through the front side and the back side, the housing comprising:
a main channel;
and
a first reference channel;
a first differential sensing element comprising a first diaphragm characterized by first diaphragm side and a second diaphragm side;
and
a first header configured to house the first differential sensing element, route pressure from the main channel to the first diaphragm side, and route pressure from the first reference channel to the second diaphragm side, the first header comprising:
a first set of header pins extending substantially perpendicular to the axis from an inner portion of the first header to an outer portion of the first header, the first set of header pins configured for electrical communication with the first differential sensing element.

5 more elements

A method, comprising:

providing a housing, the housing characterized by a front side and a back side in axial alignment along an axis extending through the front side and the back side, the housing comprising:
a main channel;
and
a first reference channel;
assembling a first header sub-assembly, comprising:
installing a first set of header pins in a first header;
attaching a first differential sensing element to the first header;
and
electrically connecting the first set of header pins to the first differential sensing element;
and
attaching the first header sub-assembly to the housing such that the first set of header pins extend substantially perpendicular to the axis from an inner portion of the first header to an outer portion of the first header.

8 more elements

providing a housing, the housing characterized by a front side and a back side in axial alignment along an axis extending through the front side and the back side, the housing comprising a main channel and at least one reference channel;
assembling a header sub-assembly, comprising:
joining a straight first reference tube to at least a first header adapter cap;
joining a straight main tube to at least one header manifold;
attaching a first differential sensing element to a first header;
installing a first set of header pins in a first header;
electrically connecting the first set of header pins to the first differential sensing element;
joining the at least one header manifold to a first side of the first header;
joining a first header adaptor cap to a second side of the first header;
and
sliding ferrules onto the corresponding straight first reference tube and the straight main tube;
and
attaching the header sub-assembly to the housing by tightening the ferrules such that the first set of header pins extend substantially perpendicular to the axis from an inner portion of the first header to an outer portion of the first header.
