Photosensitive color monitoring device and method of measurement of concentration of a colored component in a fluid

摘要: A color monitoring device is provided for measuring the concentration of a colored component in flowing gas or liquid stream which polychromatic light passed through frosted lens, then transparent sight tube passes, second mask divides into two beams, one beam passing first filter and filter, beams filters being directed to photoconductor, respectively. The absorbs absorbed by be measured passes all other light. substantially wave lengths. photoconductors are connected as resistance units null circuit such that, when enters stream, intensity unchanged while decreased due absorbance component, this difference causing an imbalance can used monitor component.
