The pressure sensor of the invention includes a pressure measuring cell and a platform through which a pressure canal equipped with a flame arrester extends. The pressure measuring cell is loadable with the process pressure through the pressure canal by means of a transmitting medium. The pressure sensor includes a first section and a second section, with the flame arrester being arranged in the first section, and the second section has a bore, in which a fill-body is arranged. The gap between the bore and the fill-body is manufactured with greater tolerances, so that it does not fulfill the requirements for a flame arrester. The flame arrester is realized in the first section, for example, by providing in the first section a bore, in which a fill-pin is arranged, with the remaining gap between the bore and the fill-pin satisfying the requirements for a flame arrester.
