Filter head probe for the gravimetric determination of the dust content in flowing gases, in particular for the assessment of dust-like emissions

摘要

the invention relates to a filterkopfsonde gravimetric determination of dust in the pouring gas in particular for the assessment of particulate emissions.$a task of the invention is a filterkopfsonde with a suction and a restraint system (11), in which errors due to contamination and losses during filter change and transportation of dust sample excluded, which low weight low detection limit has a filterkopfsonde the measurement transducers (12...17, 22) for all measures to ensure the isokinetic absaugens and the identification of teilgasstromes has and what with low transportabmessungen for mobile use in large abgaskanu00e4len is suitable.
