Sampling device for an apparatus for detecting a component in gas, in particular alcohol in exhaled air

摘要

The invention relates to a sampling device (1) for an apparatus for detecting a component in gas, in particular alcohol in exhaled air, in which a control unit (22) actuates a displaceable element (5) by application of control pulses (SA) which are the output signals of the control unit (22) whose input signals (SE) are supplied by a volume-measuring unit (21) with whose aid a volume threshold and a volume flow threshold are measured, and when they are present the displaceable element (5) is actuated directly by the control unit.
