Abstract (en)

[origin: WO2010091664A1] The present invention relates to a device and to a method for connecting an optical measuring device to a measurement volume in which a medium (2) to be measured flows. The device comprises a partition (8) for separating the optical measuring device from the measurement volume and an optical element (5) for passing optical radiance that closes off an opening formed in the partition (8). A pipe-shaped protrusion (6) is mounted on one side of the partition (8) by means of the optical element (5) such that a light or laser beam (3) can pass from an opposite side of the partition (8), through the optical element (5) and the pipe-shaped protrusion (6), into the measurement volume. One or more air inlet openings (9) are formed in the pipe-shaped protrusion (6) and/or in a connecting element between the pipe-shaped protrusion (6) and the partition (8), by means of which the ambient air (7) from outside of the measurement volume can flow into the pipe-shaped protrusion (6). The device and the method allow measurement using an optical measuring device, in a simple and cost-effective manner, wherein contamination of the optical element by the medium to be measured is prevented.
