Process connection having an annular gasket

A process connection comprising:

• an annular gasket;
• and
• a cylindrical measuring probe of a sensor,
• wherein:
• the gasket is provided to seal a process environment,
• the gasket is disposed between the process connection and the cylindrical measuring probe;
• the gasket is fixable by means of a downholder,the downholder exerting a compressive force on the gasket;
• 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;
• the gasket has a conical inner jacket surface that faces the cylindrical measuring probe the conical angle of the gasket and an outer surface of the gasket forming an acute angle with one another,
• with the gasket contacting the first annular sealing edge of the conical inner surface of the process connection;
• with the conical outer jacket angle being smaller than the conical inner angle;
• the gasket has an acute angle in cross-section at the second annular sealing edge;
• and
• the measuring probe is displaceably arranged in the gasket.
