  • Patent number: 8127615
    Abstract: A method for embossing a separating membrane of a pressure transfer means including a membrane carrier having a membrane bed. With the method, an optimal forming of the separating membrane matched to the form of the membrane bed is achievable. The method includes steps of: welding a planar, separating membrane blank onto the membrane carrier; filling with a lubricant a pressure receiving chamber enclosed by the welded, separating membrane blank and the membrane carrier; producing the separating membrane from the separating membrane blank by embossing the separating membrane blank by pressing it against the membrane bed while lubricant is present in the pressure receiving chamber.

  • Patent number: 7946148
    Abstract: A method for manufacturing-side calibration of a measuring device for capacitive fill level measurement of a medium, wherein at least one probe unit of the measuring device is activated with an electrical, alternating voltage of a predeterminable frequency. As a function of the frequency of the activating signal, a conductivity range is determined, within which the fill level measurement is essentially independent of a change of the electrical conductivity of the medium; for such conductivity range, at least a first reference matching between a predeterminable, first fill-level value and a first capacitance value belonging to the first fill-level value is produced; and the first reference matching between the first fill-level value and the first capacitance value is recorded. Additionally, the invention relates to a corresponding measuring device.

  • Patent number: 7249515
    Abstract: For minimizing the span error of a pressure sensor having an essentially cylindrical platform and a measuring membrane joined to an end face of the platform, with the pressure measuring cell being axially clamped between an elastic sealing ring, which bears against the membrane-bearing end face of the pressure measuring cell, and a support ring, which bears against the rear face of the pressure measuring cell, the dimensions of the support ring are coordinated with the dimensions of the sealing ring and pressure measuring cell such that a radial deformation of the membrane-bearing end face caused by the axial clamping of the pressure measuring cell is sufficiently small that the span error of the pressure sensor arising from a reduction of the axial clamping force by at least 10% amounts to not more than about 0.02%. Additionally, arranged between the support ring and a clamping ring is a stiff decoupling element, which minimizes the temperature hysteresis of the span.

  • Patent number: 6856142
    Abstract: The invention relates to a device for determining and/or monitoring filling of a product or the position of the boundary surface between two media or phases in a container. The device comprises a signal generating unit that generates high-frequency measuring signals, an injection unit and a surface waveguide, wherein the measuring signals are injected into the surface waveguide by means of the injection unit and directed toward the filling product via the surface waveguide. The device also comprises a receiver/evaluation unit, which directly or indirectly determines filling of the product or the position of the boundary surface in the container during the running time of the measuring signals reflected on the surface or boundary surface of the filling product. The invention aims at providing a device which is configured in such a way that parasitic voltages are effectively diverted. This is achieved in that the surface waveguide is connected to a frame potential by means of a coupling.
