  • Method for Determining the Optical Measurement Path Length in a Duct Gas Monitoring System
    Publication number: 20120236323
    Abstract: Method for determining the optical measurement path length in a duct gas monitoring system in a duct gas monitoring system configured to measure the concentration of a gas component of the duct gas from its wavelength-specific absorption light, wherein light is sent from a light source through a first purging tube, a gas duct and a second purging tube to a measuring detector, the purging tubes open into the gas duct and are flushed with a purge gas which, after flushing, is discharged into the gas duct.
