The disclosure relates to a device for converting a pressure into an electric signal. The device has a first deformation body in the form of a first membrane, via which the pressure can be introduced into the device, and a second deformation body in the form of a second membrane, by means of the deflection of which the applied pressure can be converted into an electric signal. The device has a force transmitting means for transmitting pressure and/or tensile forces from the first deformation body to the second deformation body. Either the force transmitting means is designed as a separate part and the two membranes have a bore into which the force transmitting means is at least partly introduced and in which the force transmitting means is connected to the respective membrane, or the force transmitting means is integrally formed with one of the two membranes and the corresponding other membrane has a bore into which the force transmitting means is at least partly introduced and in which the force transmitting means is connected to said membrane.

Device for converting a pressure into an electric signal, and electronic pressure measuring device comprising such a device

The invention relates to an arrangement composed of a measuring device and a container, wherein the measuring device () is suited for insertion into the container, which contains the medium to be measured, and wherein the container for receiving the measuring device () has a connector piece () having a passage opening extending in an axial direction and a seal land () projecting into the passage opening, wherein the measuring device () comprises a rotationally symmetric housing part (), which is flush with the connector piece () and has an external cone portion (), which forms with an internal cone portion () provided on the connector piece () a beveled sealing surface pair. According to the invention, the sealing element in the region of the external and internal cone portions () consists in the front end section, which faces the medium, at least partially of a plastic, especially PEEK, or an elastomer and consists in the adjoining second section (), facing away from the medium, of metal or ceramic or a fiber-reinforced plastic so that a defined and thus pressure- and force-resistant stop results in the axial direction between the external cone portion () of the measuring device () and the internal cone portion () of the connector piece (), while independently thereof the sealing function is achieved exclusively in the front end section (), facing the medium, of the sealing element ().

Screw-in arrangement composed of a measuring device and a container

A pressure measuring device comprises a capacitive pressure measuring cell, a process connector including a retaining element, a housing mounted on the process connector, and a sealing element arranged between an inwardly projecting region of the retaining element and the pressure measuring cell. The retaining element is configured with a cap with a base area portion and an outer area portion bent over with respect thereto and fitted over an end face of the process connector. The retaining element is in a material-bonded and/or form-fit manner connected to the process connector exclusively in the bent-over outer area portion so that the base area portion assumes a resilient property.

Pressure measuring device

The invention relates to an assembly, in particular for measuring a process variable, which consists of a measuring instrument having a process connection and a housing, which is partially rotationally symmetrical at least in the region of the process connection, and of an adapter having a through-hole, which extends in the axial direction, and a sealing web in the through-hole. The measuring instrument and the adapter are connected to each other in a releasable and sealed manner via two sealing surfaces. According to the invention, at least one of the sealing surfaces then has a coating composed of parylene. The invention furthermore relates to an assembly for the releasable and sealed connection of two medium-carrying parts, in particular pipelines.
