INDUSTRIAL TURBIDIMETERS WITH AUTOMATIC CLEANING OF MEASURING CELLS

摘要

The main problem in operation of industrial turbidimeters is buildup of parasitic deposits on transparent windows of light sources and photodetectors. Two different ways of solving the problem of noise-immune measurements of turbidity are discussed. The first way consists in realization of so called turbidimeters with variable gauge length. Another way lays in the field of use of photosensor arrays and image processing. In both cases presence of an automatic cleaning system is necessary.
