Abstract
A method for producing a differential pressure sensor includes steps of: introducing a rotationally-symmetrical electronics module into a cavity of a mechanical module until a contact face of the electronics module hits a stop face of the mechanical module; welding and/or gluing at least the contact face to the stop face; axial welding in an opening region of the cavity, such that the mechanical module is welded to the electronics module all around by means of the weld; filling at least two pressure transmission lines with a pressure transmission liquid, wherein the at least two pressure transmission lines are provided for the transmission of the first pressure and the second pressure from the first separating membrane and the second separating membrane, respectively, to two opposing faces of the differential pressure sensor element; and placing the housing onto the housing adapter.
