A process connection, in particular for a sensor unit in a process plant, includes an external threaded adapter that has a screw-in passage and that is provided with an internal thread; an internal threaded adapter having a cylindrical through passage and an external thread; and an annular molded seal. The external threaded adapter has a radially peripheral inwardly projecting hollow cylindrical projection at one end of the screw-in passage. The annular molded seal contacts the hollow cylindrical projection in the axial and radial direction within the screw-in passage. The external thread of the internal threaded adapter is in screw engagement with the internal thread of the external threaded adapter. The internal threaded adapter is configured to press the molded seal axially onto the hollow cylindrical projection of the external threaded adapter. The disclosure also relates to a sensor assembly having such a process connection and to a corresponding process plant.

Process connection, sensor assembly and process plant

A process connection having an annular gasket and having a cylindrical measuring probe of a sensor, wherein the gasket is provided to seal a process environment, wherein the gasket is disposed between the process connection and the measuring probe, the gasket is fixable by means of a downholder, the gasket contacts a first annular sealing edge at the process connection, the gasket surrounds the cylindrical measuring probe at a second annular sealing edge, the gasket has at least one conical outer jacket surface having a conical outer jacket angle, and the process connection has a conical inner surface having a conical inner angle, wherein the gasket contacts the first annular sealing edge of the conical inner surface of the process connection, and wherein the conical outer jacket angle is smaller than the conical inner angle.
