Sealed pressure-measuring member

The invention relates to a pressure-measuring member (12) comprising: a pressure-measuring surface (106) functionally connected to a test body (96); a sealed pressure-measuring housing (100) in which the test body (96) is placed, whereby the pressure-measuring surface (106) is borne by a deformable wall (104) of the sealed pressure-measuring housing (100) that extends at a distance from the test body and the housing (100) defines an internal space (E); means (110) for transmitting the pressure between the pressure-measuring surface (106) and the test body (96), comprising a substantially incompressible material (136) that occupies all of the internal space (E); and energy storage means (101) and means (99) for processing the pressure detected by the test body (96), provided in the sealed housing (100).
