Abstract
A relative-pressure sensor for determining a pressure of a medium in relation to an atmospheric pressure includes a housing; a measuring element arranged in the housing, wherein the pressure to be measured acts upon an outer surface of the measuring element in contact with the medium; a reference-pressure supply, which supplies an inner surface of the measuring element with atmospheric pressure in the form of ambient air, an evaluation unit, which determines the pressure of the medium from a variable determined using the measuring element; and at least one drying chamber arranged in the housing for taking up atmospheric humidity from the ambient air supplied through the reference-pressure supply. A bushing can be pressed into the housing and has a capillary-type groove, which is helical at least in sections and runs around the bushing.
