摘要： 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.

摘要： A pressure difference sensor includes a capsule, which has a ceramic capsule body. The capsule has a transducer seat in its interior, wherein there is arranged in the transducer seat a semiconductor pressure measuring transducer core, which has a measuring membrane body and at least one support body. The measuring membrane body is connected pressure-tightly with the at least one support body, which has a pressure inlet opening. Ducts extend respectively from an outer surface of the capsule into the transducer seat, wherein the pressure inlet opening communicates with the first duct A side of the measuring membrane is contactable with a pressure through the pressure inlet opening, wherein the support body contacts a joint, which surrounds the first pressure inlet opening and the opening of the first duct into the transducer seat and is connected pressure-tightly with a wall of the transducer seat, and wherein a second side of the measuring membrane is hydraulically isolated from its first side and communicates with the second duct.
