Sealing Ring and Pressure Transducer having at least one such Sealing Ring

A sealing ring for sealing in the axially clamped state, comprising:

• a metal or ceramic annular body, which has in cross section a first spring leg having at least a first sealing surface on a first end of the annular body and a second spring leg having at least a second sealing surface on a second end of the annular body, which faces away from the first end, wherein:
• between said first spring leg and said second spring leg a diagonal connecting leg extends, which is connected with said first spring leg in an inner edge region of said annular body and with said second spring leg in an outer edge region of said annular body;
• and
• said first sealing surface has a plastic sealing material, and said second sealing surface has a plastic sealing material.

A pressure measuring transducer, comprising:

• a hydraulic measuring mechanism, which has a measuring mechanism body and at least a first isolating diaphragm, which is connected with said measuring mechanism body along a peripheral joint and contactable with a medium;
• and at least one process connection body, wherein:
• said isolating diaphragm has in its edge region an annular isolating diaphragm sealing surface;
• said process connection body has a pressure output opening, by which said isolating diaphragm is contactable with the medium;
• said pressure output opening is annularly surrounded by a first process connection sealing surface;
• pressure measuring transducer furthermore has at least one sealing ring for sealing in the axially clamped state, comprising:
• a metal or ceramic annular body, which has in cross section a first spring leg having at least a first sealing surface on a first end of the annular body and a second spring leg having at least a second sealing surface on a second end of the annular body, which faces away from the first end, wherein:
• between said first spring leg and said second spring leg a diagonal connecting leg extends, which is connected with said first spring leg in an inner edge region of said annular body and with said second spring leg in an outer edge region of said annular body;
• and said first sealing surface has a plastic sealing material, and said second sealing surface has a plastic sealing material;
• and
• said sealing ring is axially clamped between said first isolating diaphragm sealing surface and said first process connection sealing surface.
