Abstract
A transducer assembly configured to accommodate a plurality of individually tunable sensing elements of various geometries and configurations by using a cap and an accompanying capillary tube. The configuration of the various embodiments described herein eliminate the header to flat plate welds of the prior art, and therefore better accommodates a plurality of sensing elements and corresponding header assemblies within one transducer assembly.
Claims20
A transducer assembly, comprising:
- a first sensing element;
- a first cap surrounding at least of portion of the first sensing element such that a first cavity is defined between the first cap and the first sensing element;
- and
- a first capillary tube having a first end and a second end, wherein the first end receives a first incoming condition stream and the second end is attached to the first cap;
- wherein the first capillary tube channels the first incoming condition stream from the first end to the second end of the first capillary tube and into the first cavity to be subsequently measured by the first sensing element.

A transducer assembly, comprising:
- a main connector housing defining a first port, the first port being adapted to receive a first incoming condition stream;
- a first capillary tube having a first end and a second end, wherein the first end of the first capillary tube is in communication with the first port and receives the first incoming condition stream;
- and
- a first cap in communication with the second end of the first capillary tube, wherein the first cap surrounds a first sensing element such that a first cavity is defined between the first cap and the first sensing element;
- wherein the first capillary tube channels the first incoming condition stream from the first end to the second end and into the first cavity to be subsequently measured by the first sensing element.
2 more elements
A method of tuning a transducer assembly, comprising:
- determining a first cavity volume based on a first tuning parameter for a first sensing element, wherein the first cavity volume surrounds the first sensing element;
- adjusting a first cap surrounding at least a portion of the first sensing element to define the first cavity volume;
- and
- determining a first distance between a first end and a second end of a first capillary tube based on the first tuning parameter;
- wherein the first end of the first capillary tube receives a first incoming stream and the second end of the first capillary tube is attached to the first cap, and wherein the first capillary tube channels the first incoming condition stream into the first cavity volume to be subsequently measured by the first sensing element.
