The invention relates to a housing comprising a venting device (10) which is arranged on the housing (2) and which allows an ambient pressure to be supplied to the interior of the housing (2). The venting device (10) is made of a sleeve-like protective cap (11) with lateral openings (12) and a liquid-repellant membrane, and a cavity for receiving the membrane is formed in the interior of the venting device (10). The membrane is arranged such that an opening, which is provided for the pressure supply, in the wall of the housing (2) is covered. In order to prevent the so-called teapot effect and therefore allow a light dripping of a liquid on the venting device (10), the sleeve-like protective cap (11) has a narrow circumferential expansion (14) in the region of the lateral surface of the protective cap such that a defined dripping edge is formed.

A pressure sensing element, including a substrate, a device layer coupled to the substrate, a diaphragm being part of the device layer, and a plurality of piezoresistors coupled to the diaphragm. A plurality of bond pads is disposed on the device layer, and an electrical field shield is bonded to the top of device layer and at least one of the bond pads. At least one stress adjustor is part of the electrical field shield, where the stress adjustor is a cut-out constructed and arranged to reduce thermal hysteresis of the pressure sensing element caused by stress relaxation of the electrical field shield during a cooling and heating cycle. The stress adjustor may be a thin film deposited on top of the electrical field shield, which may apply residual stress to the piezoresistors.
