Abstract: A pore-free weld connection and a method for manufacturing such a weld connection between first, second and third components (1, 3, 5, 13, 15, 17), which are connected together by means of a closed weld seam (7, 18), and of which one component (5, 17) has, at a start- and end-point (9, 11, 21, 23) of the weld seam (7, 18), a cavity (6, 19) serving for a root-side degassing of a weld puddle.

Abstract: A pressure sensor element for mounting in a connecting element comprises an isolator body with a laterally projecting membrane. The laterally projecting membrane covering an opening of a passage through which the pressure present at the surface of the membrane is conveyed to a pressure transducer element by means of a hydraulic fluid. In order to mount the pressure sensor element, it is secured in a mounting aperture of the connecting element. The projecting perimeter of the membrane is secured to the surface surrounding the mounting aperture of the connecting element by means of a continuous seam. A membrane type ring in combination with a conventional membrane may be substituted for the projecting membrane, wherein the membrane type ring covers the gap between the pressure sensor element and the adapter element.

Abstract: A device for determining and/or monitoring the level of a medium in a container or for ascertaining the density of a medium in the container embodied as a vibration detector. According to the invention the vibration detector still functions reliably even under extreme process conditions and upon abrupt changes in process conditions. The vibration detector has a tubular inner part provided, which is dimensioned such that it is positioned between the housing wall and a drive/receiving unit, and that the tubular inner part is connected to the housing or to the diaphragm.

Abstract: The invention relates to a vibration detector (1) for determining and/or monitoring the level of a medium in a container or for ascertaining the density of a medium in the container.

Abstract: A pressure sensor element for mounting in an adapter element (40) comprises an isolator body (10) with a laterally protecting membrane (20). The membrane (20) covers an opening of a passage (12) through which the pressure present at the surface of the membrane (20) is conveyed to a pressure transducer element (30) by means of a hydraulic fluid (32). In order to mount the pressure sensor element, it is secured in a mounting aperture of the adapter element (40). The projecting perimeter of the membrane (20) is secured to the surface surrounding the mounting aperture of the adapter element (40) by means of a continous seam. A membrane type ring in combination with a conventional membrane may be substituted for the projecting membrane, wherein the membrane type ring covers the gap between the pressure sensor element and the adapter element.
