Patent ID: 8490494

Claim:
A relative pressure sensor for registering the pressure of a medium relative to surrounding atmospheric pressure, comprising: 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; and a support body, through which a reference air duct extends between a first surface section and a second surface section of said support body; and a shield element, which protects a bonded adhesive from direct contact with reference air, wherein: said pressure measuring cell is affixed to said support body with said pressure resistant, bonded adhesive; said reference air opening communicates with said reference air duct, in order to form a reference air path to the measuring membrane; and said bonded adhesive surrounds said reference air path.
