Optical measuring cell for use in gas monitor, has light source for transferring light into measuring volume that is represented by inner volume of hollow fiber whose inner diameter is less than 1 millimeter
Optical measuring cell for use in gas monitor, has light source for transferring light into measuring volume that is represented by inner volume of hollow fiber whose inner diameter is less than 1 millimeter
The cell has a light source (2) for transferring light into a measuring volume, and an optical receiver (3) approximately opposite with respect to the volume and in direction of light propagation of the light source. The receiver receives the light guided through the volume, and an evaluation unit (4) determines concentration of target gases in a measuring gas volume. The measuring volume is represented by an inner volume of a hollow fiber (1) whose inner diameter is less than 1 millimeter. A gas conveyer system fills the measuring volume with either measuring gas or purge gas.
