Turbidity sensor comprises infrared/blue light emitting diode with a luminescence transducer, measuring photo receiver, circuit for the operation in each diode in the pulse process and an analysis circuit signals emitted by the detector

摘要

The photo receiver emits an intensity-measuring signal for the conception of the light strewn by a sample. The sensor exhibits reference receiver for the determination of the intensity of the radiation of the diodes and a band pass/edge filter in a lighting path of the diodes. The path exhibits a beam splitter in order to decouple a part of the radiation to the receiver. The diode reference light path is extended to the receiver, which is perpendicular to the lighting path.
