Abstract

A relative pressure sensor for registering pressure of a medium relative to surrounding atmospheric pressure includes: a pressure measuring cell having a measuring membrane and a platform, wherein pressure of the medium can act on a first side of the measuring membrane facing away from the platform, and wherein the platform has a reference air opening, through which surrounding atmospheric pressure can act on a second side of the measuring membrane facing the platform. A support body, through which a reference air duct extends between a first surface section and a second surface section of the support body is provided, wherein the pressure measuring cell is affixed to the support body with a pressure resistant, bonded adhesive. The reference air opening communicates with the reference air duct, in order to form a reference air path to the measuring membrane, wherein the bonded adhesive surrounds the reference air path, and the relative pressure sensor further includes a shield element, which protects the bonded adhesive from direct contact with reference air.
