This partial current is continuously heated and diluted with clean, heated air directly in the sampling probe. This immediately lowers the relative moisture and aerosols get evaporated in the heated System for continuous extractive dust concentration ­measurement in accordance with the scattered light principle probe. The partial current is optically measured in the measuring chamber. The signal is corrected by the measured dilution ratio and is thus a measure of the dust content of the exhaust gas. The system comprises a special sampling probe, the laser dust monitor, a gas conditioning unit (dilution, tempering), an injector, two fans and an electronic evaluation unit. The sampling probe and the measuring chamber form an assembly. The electronic evaluation unit and one blower for operating the injector and one for generating the diluting air are mounted together on a rack frame.
