Beschreibung
Zusammenfassung:	This invention relates to a fluid sealing device comprising a sealing member comprising a first surface and an opposite second surface. A first region of the first surface for forming a first seal about an aperture of a process component containing a fluid, and an inner region of the first surface to be exposed to the fluid via the process component aperture. A restraining member providing a support surface facing the second surface, a perimeter portion of the restraining member interfacing with a first region of the second surface, the first regions of the first and second surfaces corresponding with a first region of the sealing member. An inner region of the second surface spaced from the support surface to form a cavity between the inner region of the second surface and the supporting surface at least in an unpressurised condition. The inner regions of the first and second surfaces corresponding with an inner region of the sealing member, the inner region of the sealing member moveable towards and away from the support surface under action of a pressure of the fluid on the inner region of the first surface to provide an indication of the pressure.
