Abstract
A relative-pressure sensor determines the pressure of a medium in relation to an atmospheric pressure. The sensor includes a housing having a measuring element located in the housing, wherein the pressure to be measured acts upon an outer surface of the measuring element. The surface is in contact with the medium. The sensor also includes a reference-pressure supply, which supplies an inner surface of the measuring element with atmospheric pressure in the form of ambient air, and an evaluation unit, which determines the pressure of the medium from a variable determined using the measuring element. A drying chamber takes-up atmospheric humidity from the ambient air that is supplied via the reference-pressure supply. The drying chamber has a drying module comprising a container and a humidity-adsorbing material that is completely surrounded by the container.
