Gas-conducting system e.g. gas washer, monitoring arrangement, for use in process industry, has measuring and comparison cuvettes introduced into gas-conducting system via conducting path, where gas flows through cuvettes

摘要

The arrangement has a non-dispersive infrared gas analyzer (6) with a measuring cuvette (10) and a comparison cuvette (11). The analyzer is designed as a two-beam type analyzer, where the two cuvettes are respectively irradiated by two beams. The measuring cuvette is inserted into a conducting path (24) of a gas-inlet (2) and the comparison cuvette is inserted into a conducting path (25) of a gas-outlet (3) so that the cuvettes are introduced into a gas-conducting system (1) via the respective path and gas (4) that is guided out of the system flows through the cuvettes.
