Patent ID: 7938019

Claim:
Sealed electrode assembly for fluid measurements in a pressurized pipe or container having a wall, for providing contact between an electrode in contact with the fluid and the outside, said assembly comprising a conductive bolt extending from said electrode and through the wall, and further comprising: a first lining in said pipe or container of a resilient and sealing material having an opening for said bolt and insulating the electrode from the wall, a first sealing ring fitted around the bolt, said first lining being between the first sealing ring and the electrode, a mantel surrounding said bolt having an essentially conical first recess partially accepting said first sealing ring and provided a radial pressure on said first sealing ring when pressed into said recess, and a tightening means on the outside of said wall for applying a pressure forcing the electrode toward the wall and thus a pressure between said first lining, said first sealing ring and said mantel, at least two of: said first lining, said first sealing ring, and said mantel are made from materials being resistant against chemical exposure, mechanical wear and temperature variations, said at least two of: said first lining, said first sealing ring and said mantel constituting a pair of mutually sealing parts that are made from different materials.
