    摘要: An adapter (1) and electrochemical gas sensor (2) is provided with an electrochemical gas sensor housing (14) accommodating an electrolyte (13), with at least one measuring electrode (12) arranged therein and with a membrane (11), which screens the measuring electrode (12) from a measured gas and is permeable to the measured gas. The measuring sensitivity of an electrochemical gas sensor is increased by the adapter (1) having a gas-impermeable surface (15) extending in parallel to and at a spaced location from the membrane (11). The adapter (1) and the membrane (11) form a flow gap (10) for the measured gas delivered by a pump. The adapter (1) may be plugged onto the electrochemical sensor (2) at its outer edge (1a). The measured gas enters through a central opening (17), expands in the flow gap (10) radially to the outside and leaves same via the ring-shaped gap (16).

    摘要: A switch cabinet is provided for protection of servers and other highly sensitive computer devices or miscellaneous equipment. The cabinet is configured as a protection cabinet with an interior isolated from the atmosphere. The interior is continuously provided with fresh air by a ventilator. Fresh air is controlled by early detection fire sensors shortly before passing through the ventilator. When fire breaks out, the early detection fire sensors activate gas bottles filled with the noble gas argon, so that argon can be introduced into the interior to extinguish the fire once fresh air supply has been stopped, thereby ensuring early and fast extinguishing of the blaze.
