Gas mixer

For a homogeneous mixing of two or more gases, the gas mixture is continuously analysed. With help of proportional valves the mixture is fed  in an exact ratio to a background gas. Various analysis methods, e.g. TCD, NDIRE, UV, fuel cells, etc) can be used to analyze the gases to be supplied. The analysis are read out via a PID controller , which controls the proportional valves. The gases are mixed in a chaos demister and, if necessary, a buffering can be done with an additional volume. The gas mixer can store internally analogue and limit values and make them available for further processing via a terminal block. In case  toxic or explosive gas mixtures, the interior of the controller can be checked for leaks.   With the gas mixer also contaminated gases can be precleaned and mixed.
