Optical transducers used to the determination of biocomponent content in diesel oil

摘要

The system which allows to determine the amount of rapeseed oil methyl esters (RME) in diesel is presented and described. The parameters and characteristics of different light sources and photodetectors were tested in order to choose the proper basic elements of the optical device. The spectral characteristics of the elements were analysed in view of the absorption spectrum properties as well. The results of RME content measurements were presented and the usefulness of the designed measuring system was discussed.
