Der photoelektrische Aerosolsensor (PAS), ein neues direkt anzeigendes Messgerät für Dieselmotoremissionen

A novel sensor system, the photoelectrical aerosol sensor (PAS), was checked for its applicability in the field of investigations of diesel particulate matter in workplace air. The work was sponsored by the German federation of institutions for statutory accident insurance and prevention (Hauptverband der gewerblichen Berufsgenossenschaften). As comparing method the coulometric determination of elementary carbon in the respirable dust fraction was used. Several measurement campaigns were performed on an engine test stand as well as in different types of workplaces. The PAS were found to be well-suited for certain types of measurement tasks. Recommendations for use are given. A detailed research report is available.
