  • Pressure resistently encapsulated, pressure difference sensor
    Patent number: 9054222
    Abstract: 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.
    Type: Grant

  • Relative pressure sensor
    Patent number: 8490494
    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.
