Abstract

A multi-channel pressure measuring device includes a plurality of sample conduits and a plurality of sample inlets. Each sample inlet is configured to receive a respective sample conduit. The sample conduit is configured to channel a sample fluid and an incidental fluid through a respective sample inlet. The multi-channel pressure measuring device also includes a sample block including a plurality of collection wells coupled to the sample inlets. Each collection well includes a diameter larger than a diameter of a respective sample inlet. The sample block is fabricated from at least one of a transparent material and a translucent material. The multi-channel pressure measuring device further includes a plurality of filter indicator elements. Each filter indicator element is positioned within a respective collection well. Each filter indicator element is configured to retain the incidental fluid therewithin and to indicate a presence of the retained incidental fluid.

First claim

What is claimed is:

1. A multi-channel pressure measuring device comprising:
a plurality of sample conduits;
a plurality of sample inlets, each sample inlet of said plurality of sample inlets configured to each receive a respective sample conduit from said plurality of sample conduits, said sample conduit configured to channel at least one of a sample fluid and an incidental fluid through a respective said each sample inlet;
a sample block comprising a plurality of collection wells coupled to said plurality of sample inlets, each said collection well of said plurality of collection wells comprising a diameter larger than a diameter of a respective said sample inlet, said sample block fabricated from at least one of a transparent material and a translucent material;
a plurality of filter indicator elements, each filter indicator element of said plurality of filter indicator elements positioned within a respective collection well, said each filter indicator element configured to retain the incidental fluid therewithin and to indicate a presence of the retained incidental fluid; and
a pressure scanner in fluid communication with the sample inlets and which has sensors configured to measure pressure within the pressure scanner.

2. The multi-channel pressure measuring device of claim 1 , wherein said filter indicator element comprises an oleophilic material.

3. The multi-channel pressure measuring device of claim 1 , wherein said filter indicator element comprises at least one of a filter paper, a ceramic material, and a fiberglass material.

4. The multi-channel pressure measuring device of claim 1 , wherein said sample block comprises at least one of a polycarbonate resin, a polymethyl methacrylate material, and a glass material.

5. The multi-channel pressure measuring device of claim 1 , wherein said incidental fluid comprises oil.

6. The multi-channel pressure measuring device of claim 1 , wherein said sample fluid comprises pressurized gas.

7. A method of measuring pressure comprising:
receiving a plurality of sample conduits from a plurality of measured locations to a plurality of sample inlets, each sample conduit of the plurality of sample conduits containing a sample fluid and an incidental fluid, each respective sample conduit of the plurality of sample conduits channeling the sample fluid and the incidental fluid from an associated measured location of the plurality of measured locations to an associated sample inlet of the plurality of sample inlets;
channeling the sample fluid and the incidental fluid from the plurality of sample inlets to a plurality of collection wells, each respective sample inlet of the plurality of sample inlets channeling the sample fluid and the incidental fluid to an associated collection well of the plurality of collection wells;
detecting a presence of the incidental fluid in at least one of the collection wells of the plurality of collection wells;
visually indicating the presence of the incidental fluid; and
measuring the pressure of the plurality of measured locations using a pressure scanner which is in fluid communication with the sample inlets.

8. The method of claim 7 , wherein the detecting of the presence of the incidental fluid in at least one of the collection wells comprises contacting the incidental fluid with a filter indicator element.

9. The method of claim 7 , wherein the visually indicating of the presence of the incidental fluid comprises visually indicating a filter indicator element.

10. The method of claim 7 , wherein the receiving of the plurality of sample conduits from each of the plurality of respective measured locations to the plurality of sample inlets comprises receiving a plurality of pressurized gas samples from each of the plurality of respective measured locations to the plurality of sample inlets.

11. The method of claim 7 , wherein the detecting of the presence of the incidental fluid in at least one of the collection wells comprises detecting a presence of oil in at least one of the collection wells.

12. The method of claim 7 , wherein the detecting of the presence of the incidental fluid in at least one of the collection wells comprises contacting the incidental fluid with at least one of a filter paper, a ceramic material, and a fiberglass material.

13. The method of claim 7 , wherein the channeling of the sample fluid and the incidental fluid from each respective sample inlet to an associated collection well comprises channeling the sample fluid and the incidental fluid from each respective sample inlet to a sample block comprising the plurality of collection wells for each sample inlet of the plurality of sample inlets, said collection wells each comprising a diameter larger than a diameter of a respective sample inlet, said sample block formed of at least one of a transparent material and a translucent material.

14. A system for indicating a presence of oil in a pressure sensor comprising:
a test device comprising a plurality of measured locations;
a pressure measuring device comprising:
a plurality of sample conduits, each measured location of said plurality of measured locations configured to each receive a respective sample conduit from said plurality of sample conduits, said sample conduit configured to channel at least one of a sample fluid and an incidental fluid from a respective said each measured location;
a plurality of sample inlets, each sample inlet of said plurality of sample inlets configured to each receive a respective sample conduit from said plurality of sample conduits, said sample conduit configured to channel at least one of said sample fluid and said incidental fluid through a respective said each sample inlet;
a sample block comprising a plurality of collection wells coupled to said plurality of sample inlets, each said collection well of said plurality of collection wells comprising a diameter larger than a diameter of a respective said sample inlet, said sample block fabricated from at least one of a transparent material and a translucent material; and
a plurality of filter elements, each filter indicator element of said plurality of filter indicator elements positioned within a respective collection well, said each filter indicator element configured to retain the incidental fluid therewithin and to indicate a presence of the retained incidental fluid.

15. The system of claim 14 , wherein said filter indicator element comprising an oleophilic material.

16. The system of claim 14 , wherein said filter indicator element comprises at least one of a filter paper, a ceramic material, and a fiberglass material.

17. The system of claim 14 , wherein said sample block comprises at least one of a polycarbonate resin, a polymethyl methacrylate material, and a glass material.

18. The system of claim 14 , wherein said incidental fluid comprises oil.

19. The system of claim 14 , wherein said sample fluid comprises pressurized gas.

20. The system of claim 14 , wherein said testing device comprises a gas turbine engine.
