A pressure sensor assemblage includes a housing and a pressure sensor received in an interior space of the housing. The housing has at least one gas inlet that is connected in gas-permeable fashion at least to a sub-region of the interior space of the housing. In addition, a sacrificial element is provided at the gas inlet, which element is disposed and implemented in such a way that gas flowing through the gas inlet comes into contact with a surface of the sacrificial element, which surface of the sacrificial element is provided with a silver layer. The sacrificial element has a carrier element made of an iodine- or iodide-resistant material.
