Device for detecting a pressure of a fluid medium and method for manufacturing the device

An apparatus for detecting a pressure of a fluid medium, the apparatus comprising:

• at least one housing with at least two pressure feed lines;
• at least one sensor module, the sensor module being received in the housing, wherein the sensor module includes:
• at least one carrier element having at least one substrate and at least one molding compound, the carrier element having at least one passage opening, the passage opening penetrating the carrier element completely;
• and
• at least one pressure sensor element for detecting the pressure and including at least one membrane, the pressure sensor element covering the passage opening, wherein:
• the sensor module includes at least one control and evaluation unit,
• the control and evaluation unit includes at least one application-specific integrated circuit and is enclosed at least partially by the molding compound,
• the housing includes at least one first housing part and at least one second housing part,
• the first housing part and the second housing part are connected to one another in an integrally joined manner,
• the pressure sensor element includes an upper side and a lower side,
• the membrane is situated on the upper side,
• the lower side faces the substrate,
• the sensor module is received in the housing in such a way that the upper side faces the first housing part,
• a first pressure duct and a second pressure duct are configured in the first housing part,
• the first pressure duct is connected to a first pressure feed line,
• the second pressure duct is connected to a second pressure feed line, the first pressure duct is configured in such a way that the pressure sensor element can be loaded from the lower side with a first pressure,
• the second pressure duct is configured in such a way that the pressure sensor element can be loaded from the upper side with a second pressure,
• the first pressure duct is of substantially U-shaped configuration with a bottom section and two limb sections, and
• the second pressure duct extends through between the two limb sections.
