Relative pressure sensor

A relative pressure sensor, comprising:

• a pressure measuring transducer, having a measuring membrane of a semiconductor chip;
• a platform, wherein between said measuring membrane and said platform, a reference pressure chamber is formed, a support body, wherein said platform is connected with said support body by means of a pressure-bearing adhesion;
• and
• a sensor outer body, in which a transducer chamber is formed, said transducer chamber has a first opening and a second opening, wherein said pressure measuring transducer is brought into said transducer chamber through said first opening, and is held in said transducer chamber by means of said support body, said support body pressure-tightly seals said first opening, wherein:
• a reference pressure path extends through said platform and said support body, in order to introduce reference pressure into said reference pressure chamber;
• a side of said measuring membrane facing away from said reference pressure chamber is contactable with the media pressure through said second opening, characterized in that the reference pressure path has a gas-filled, sealed section, which extends from said reference pressure chamber at least through said pressure bearing adhesion;
• and
• said sealed section is gas-tightly sealed by means of a flexible, metallized plastic foil.
