Abstract
A pressure sensor () for a measuring system () measuring concentrations of gaseous and/or aerosol components of a gas mixture with a reaction carrier (), with a flow channel (). The flow channel () forms a reaction chamber () with a reactant (), that enters into an optically detectable reaction, and with a measuring device () with a gas port unit () connecting an inlet channel () and an outlet channel () to the flow channel () and a gas delivery unit (). The pressure sensor () measures a pressure difference of a gas mixture flowing through the gas delivery assembly unit () and/or the flow channel () of the reaction carrier () and has an elastic element (), which is configured to undergo deformation as a function of the pressure difference. A measuring method, a measuring device and a reaction carrier for such a measuring system are also provided.
