A connection adapter for connecting a process chamber to a measuring system, in particular to a pressure, density or temperature measuring system, which includes at least three ports, having a process port, the process port being connected or connectable to the process chamber, a measuring port, the measuring system being connected or connectable to the measuring port, and an access port, which includes a self-sealing coupling. The connection adapter, furthermore includes a line system, having lines and at least one closable shutoff device. The line system connecting the process port to the measuring port and the access port, the connection between the process port and the measuring port being blockable gas-tight with the aid of the shutoff device, and the access port being connected or connectable to the measuring port via the line system. A measuring apparatus having a connection adapter is also provided.

Connection adapter as a test port, including shutoff device

A sensor system for determining physical variables of a switchgear assembly having a sensor connection, which is designed for connection to the switchgear assembly, within which a humidity sensor and/or a pressure sensor and a light sensor for detecting light flashes are arranged. A switchgear assembly is provided that is filled, in particular, with a protective gas, comprising at least one such sensor system.
