A potting shell, for an electronic circuit on a circuit board, comprises a wall arrangement, which defines a shell volume at least in one spatial direction and in the directions perpendicular thereto; wherein the circuit board is positionable in the shell volume, and can be potted in the shell volume with a potting compound. The volume between the circuit board and a main wall of the potting shell, running essentially parallel, at least sectionally, to the circuit board, can be filled with a potting compound, characterized in that the main wall has at least one flexible section, which, based on a thermal expansion of the potting compound, can be deformed perpendicular to the plane of the flexible section.

Potting shell

A relative pressure measuring transmitter resistant to the intrusion of moisture. includes a housing, an insert arranged in the housing, a gap existing between the housing and the insert, a relative pressure sensor, and, connected to the relative pressure sensor, a reference pressure supply line, which leads into the insert, opens on an outer wall of the insert, and has an interior, which is connected via an opening in insert with the gap The housing has a bore passing through it, via which the gap is placed in communication with an environment of the relative pressure measuring transmitter.
