1. A pressure sensor with a cover, the pressure sensor comprising
a pressure sensor element;
a pressure sensor housing accommodating the sensor element, the cover being configured to cover the pressure sensor element and for providing an internal cavity in-between the cover and the sensor element, the cover comprising:
a membrane made from a flexible material and defining at least a part of a wall member between the internal cavity and the exterior of the cover for communicating pressure from the exterior of the cover into the internal cavity, or vice versa, by flexing the membrane;
one or more venting openings extending from the exterior surface of the cover and into the internal cavity, wherein the cover is configured to co-operate with the pressure sensor to fluidicly seal the internal cavity with the pressure sensor so as to allow fluid communication between the exterior of the cover and the internal cavity though said one or more venting openings.
