Claims
- 1. A gas sensor shield, comprising:
an elongated body comprising solid sides and a tip disposed across one end of said shield; and an opening disposed within said tip, wherein said opening comprises at least two elongated apertures.
- 2. The shield of claim 1, wherein said tip has a geometry selected from the group consisting of rounded and dome-like.
- 3. The shield of claim 1, wherein the opening comprises at least three elongated apertures.
- 4. The shield of claim 3, wherein said apertures have a width of about 0.25 mm to about 2.0 mm, and a length of about 2.0 mm to about 5.0 mm.
- 5. The shield of claim 4, wherein said width is about 0.50 mm to about 2.0 mm, and said length is about 2.5 mm to about 4.0 mm.
- 6. The shield of claim 5, wherein said width is about 1.0 mm to about 1.5 mm, and said length is about 3.0 mm to about 3.5 mm.
- 7. The shield of claim 3, wherein said apertures have a width of about 0.5 to about 1.5, and a length of about 2.5 mm to about 3.5 mm.
- 8. The shield of claim 3, wherein said apertures each have a geometry selected from the group consisting of triangular, rectangular, trapezoidal, square, and combinations comprising at least one of the foregoing shapes.
- 9. The shield of claim 8, wherein at least one of said apertures is formed by a series of holes.
- 10. The shield of claim 1, wherein said opening comprises three slits disposed at 120° angles from one another.
- 11. The shield of claim 1, wherein the opening comprises four slits disposed at 90° angles from one another.
- 12. The shield of claim 1, wherein said opening has a geometry selected from the group consisting of triangular, Y-like shape, T-like shape, star-like, two perpendicular lines, rectilinear, and combinations comprising at least one of the foregoing geometries.
- 13. The shield of claim 1, wherein said apertures have a substantially constant width.
- 14. A method for manufacturing a gas sensor shield, comprising:
disposing a sensing element in electrical communication with a wiring harness, wherein said wiring harness is disposed within an upper shell; disposing a shield over at least a lower portion of said sensing element, wherein said shield comprises an elongated body comprising solid sides and a tip disposed across one end of said shield, and an opening disposed within said tip, wherein said opening comprises at least two elongated apertures.
- 15. A method for sensing gas, comprising:
exposing a gas sensor to a gas stream, said gas sensor comprising a sensing element in electrical communication with a wiring harness, wherein said wiring harness is disposed within an upper shell, and a shield disposed over at least a lower portion of said sensing element, wherein said shield comprises an elongated body comprising solid sides and a tip disposed across one end of said shield with an opening disposed within said tip, wherein said opening comprises at least two elongated apertures; passing gas through said opening to said sensing element; and determining the concentration of at least one component of said gas.
- 16. The method of claim 11, wherein said tip has curved area disposed in between the top of said tip and said body, wherein said opening is disposed within said curved area.
