Abstract
For measuring pressure or differential pressure, in particular for highly viscous and/or glutinous foodstuffs, provision is made for a device which exhibits a ceramic pressure sensor (1), a housing (2) and a connection element (3) which is connected releasably to the housing (2) and is intended for fastening the device on a wall (6) of a container which contains a measuring medium. Furthermore, two sealing elements (4, 9) which engage around one another coaxially are provided: an outer sealing element (4) which is located between the housing (2) and the pressure sensor (1), on the side facing the measuring medium, and an inner, exchangeable sealing element (9) which is arranged between the pressure sensor (1) and the connection element (3).

A device for measuring pressure or differential pressure of a measuring medium in a container, having
- a ceramic pressure sensor (1) having a side facing the measuring medium,
- a housing (2) containing the pressure sensor (1),
- a connection element (3) which is connected releasably to the housing (2) and is intended for fastening the device on a wall (6) of the container which contains the measuring medium,
- an outer sealing element (4) which is inserted between the housing (2) and pressure sensor (1) and
- an exchangeable inner sealing element (9) which is inserted between the pressure sensor (1) and connection element (3), the inner sealing element engages the pressure sensor (1) on the side of the pressure sensor (1) facing the measuring medium;
- the sealing elements are arranged coaxially with the outer sealing element (4) having a larger diameter than the inner sealing element (4).
