Abstract
A seal for a depth gauge having an axis of revolution, the seal including a radially inner flank and a radially outer flank, wherein the radially inner flank has a height (h1) greater than a height (h2) of the radially outer flank. Also, a depth gauge with the seal.
Claims9
A depth gauge comprising:
- a case closed by a bottom, said bottom delimiting a pressure chamber in fluidic communication with the outside of the depth gauge,
- a pressure sensor comprising a deformable membrane disposed above said pressure chamber;
- and
- a seal including a radially inner flank and a radially outer flank, the radially inner flank having a height greater than a height of the radially outer flank in an un-deformed state, said seal being sandwiched between the deformable membrane and the bottom to ensure tightness of said case in relation to said pressure chamber including when the deformable membrane is in a deformed state,
- wherein the bottom and the deformable member are devoid of a channel or a groove for housing said seal such that said seal is not retained in any channel or groove.
