Claims
- 1. An apparatus for holding a sensor for sensing the contents of a vessel, the vessel having a wall, the apparatus having an extended position where the sensor is exposed to the contents and a retracted position for cleaning the sensor, the apparatus comprising:
a process connection configured to connect the apparatus to the wall of the vessel, the process connection defining an aperture including a first rim, a second rim angularly displaced from the first rim, and a sidewall extending between the first rim and the second rim; wherein the sidewall is angularly displaced from the first rim by no less than 135 degrees.
- 2. The apparatus of claim 1, wherein when the apparatus is in the extended position, the sensor extends beyond the first rim of the aperture into the vessel.
- 3. The apparatus of claim 2, wherein the first rim intersects the second rim to form an angle therebetween.
- 4. The apparatus of claim 3, further comprising:
a sensor chamber closed at one end by a cap having a face facing the wall; wherein when the apparatus is in the retracted position, the face of the cap is substantially in the same plane as the first rim of the aperture.
- 5. The apparatus of claim 4, wherein when the apparatus is in the retracted position, the face of the cap is spaced apart from the first rim by no more than {fraction (3/16)} inches.
- 6. The apparatus of claim 4, wherein the process connection includes a first member configured to be attached to the wall of the vessel, the first member including the first rim and the second rim.
- 7. The apparatus of claim 6, wherein the process connection further includes a second member coupled to the first member and a fluid tight seal interposed between the first member and the second member.
- 8. The apparatus of claim 7, wherein angle between the first rim and the second rim is not less than 5 degrees and not more than 15 degrees.
- 9. The apparatus of claim 8, wherein the sidewall is straight.
- 10. A process connection for connecting a sensor holder to an opening in a wall of a vessel, the process connection comprising:
a connector configured to be coupled to the sensor holder and further configured to be coupled to the wall of the vessel, the connector defining an aperture including a first rim, a second rim angularly displaced from the first rim, and a sidewall extending between the first rim and the second rim; wherein the sidewall is angularly displaced from the first rim by no less than 135 degrees.
- 11. The process connection of claim 10, wherein the connector includes a first member configured to be attached to the wall of the vessel, the first member including the first rim and the second rim.
- 12. The process connection of claim 11, wherein the connector further includes a second member coupled to the first member and a fluid tight seal interposed between the first member and the second member.
- 13. The process connection of claim 12, wherein the sidewall is straight.
- 14. The process connection of claim 13, wherein the second rim is angularly displaced from the first rim by not less than 5 degrees and not more than 15 degrees.
- 15. The process connection of claim 14, wherein the first rim intersects the second rim.
