Housing with ventilation sleeve as well as measuring device and pressure measuring device for process measurement technology with such a housing

摘要

The invention relates to a housing with a ventilation device (10) arranged on the housing (2), which enables the supply of ambient pressure to the interior of the housing (2), the ventilation device (10) consisting of a sleeve-like protective cap (11) with lateral Openings (12) and a liquid-repellent membrane (13) is formed and a cavity for receiving the membrane (13) is formed inside the venting device (10) and the membrane (13) is arranged so that an opening provided for the pressure supply is covered in the wall of the housing (2). In order to avoid the so-called teapot effect and thus allow a slight dripping of a liquid on the ventilation device (10), the invention provides that the sleeve-like protective cap (11) in the area of its side surface is narrow , has circumferential widening (14), so that a defined drip edge is formed.
