Abstract
A device for detecting a content of critical gas in a mining chamber of a tunnel boring machine includes a separation module by which a fluid fed in via an extraction line connection is cleaned of solid and liquid components. A gas line arrangement arranged downstream of the separation module in the flow direction of the fluid carries the fluid, including substantially only gaseous components, through a pressure reducer and through a flow control valve of a metering module by which the gas to be analyzed can be delivered in a controlled manner assisted by a double diaphragm pump and a pressure stabilizer to a gas analysis unit even at high pressures in the cavity.
