The invention relates to a housing comprising a venting device () which is arranged on the housing () and which allows an ambient pressure to be supplied to the interior of the housing (). The venting device () is made of a sleeve-like protective cap () with lateral openings () and a liquid-repellant membrane, and a cavity for receiving the membrane is formed in the interior of the venting device (). The membrane is arranged such that an opening, which is provided for the pressure supply, in the wall of the housing () is covered. In order to prevent the so-called teapot effect and therefore allow a light dripping of a liquid on the venting device (), the sleeve-like protective cap () has a narrow circumferential expansion () in the region of the lateral surface of the protective cap such that a defined dripping edge is formed.

Housing with venting sleeve and measuring device, and pressure measuring device for process measuring, comprising such a housing

A pressure measuring device comprises a capacitive pressure measuring cell, a process connector including a retaining element, a housing mounted on the process connector, and a sealing element arranged between an inwardly projecting region of the retaining element and the pressure measuring cell. The retaining element is configured with a cap with a base area portion and an outer area portion bent over with respect thereto and fitted over an end face of the process connector. The retaining element is in a material-bonded and/or form-fit manner connected to the process connector exclusively in the bent-over outer area portion so that the base area portion assumes a resilient property.

Pressure measuring device

A ceramic pressure measurement cell for use in a sensor for static and/or dynamic monitoring of the pressure of a liquid or flowable medium which includes a base body and a membrane connected to the base body such that one side of the membrane is in contact with the medium to be monitored. The pressure measurement cell has high chemical resistance and high temperature resistance for a plurality of chemicals which is achieved by applying at least one plastic film on the side of the membrane in contact with the medium.
