  • Publication number: 20240053311
    Abstract: A gas detector (100) includes a housing (1), a sensor in the housing and an adapter (3, 3.1). An inlet in the housing provides a fluid connection between the sensor and the environment. The sensor is configured to measure a detection variable that correlates with the concentration of a target gas to be detected. The adapter (3, 3.1) can be detachably and fluid tightly mounted on the housing. A fluid guide unit can be connected to a connection element (12, 12.1) of the adapter (3, 3.1). When the adapter (3, 3.1) is attached, an elastic filling (6, 6.1) is located between an outer shell (9, 9.1) of the adapter (3, 3.1) and the sensor. The filling (6, 6.1) is made of a cured foam. The foam includes fluorinated rubber. A channel (10, 10.1) in the filling provides a fluid connection between the connection element (12, 12.1) and the sensor.

  • Patent number: 10369322
    Abstract: A breathing apparatus includes a compressed air source with a compressed air source valve, a breathing regulator with a pressure reducer and a demand valve, a breathing mask connected to the demand valve at a first inlet connector, a second air source, a switching mechanism having an actuating member for switching between the compressed air source and the second air source and an exhalation valve, on the breathing mask, movable between a higher internal pressure in a second operating state than in a first operating state. The actuating member is provided on the breathing regulator. The switching mechanism, upon being switching to compressed air breathing, activates the lung-governed demand valve and adjusts the exhalation valve to the second operating state. Upon switching to breathing via the second air source, the lung-governed demand valve is deactivated and the exhalation valve (30) is adjusted to the first operating state.
