OPTICAL SENSOR SYSTEM ON AN APPARATUS FOR TREATING LIQUIDS

摘要

An optical sensor system on an apparatus for treating liquids, with .cndot. a device for projecting light to at least one illumination position in space, .cndot. at least one device for imaging the at least one illumination positi on on at least one photo detector in order to supply a measurement signal depending on the received light, .cndot. wherein the device for projecting is a device for simultaneously projecting light to plural illumination positions and/or the device for projecting is a device for simultaneously projecting light under different angles to the same illumination position, and/or plural photo detectors are existent, and .cndot. an analysing unit connected to the at least one photo detector for analysing the at least one measurement signal.
