PFM 97 ED

Jatkuvatoiminen pölyanalysaattori kosteille kaasuille, triboelektronisilla antureilla Fields of application
The dust concentration measuring device PFM 97 ED is used for the continuous extractive measurement of dust contents in wet and sticky exhaust gases.
By means of a temperature-regulated probe the measuring gas is extracted from the process and led to the measuring chamber where the triboelectric dust sensors are placed.
In order to produce evaluable measuring signals and to protect the triboelectric measuring cell respectively the gas lines of the measuring device the measuring gas sucked off is continuously heated and diluted with dry and dust-free ambient air. Ominaisuudet: The active principle of the dust measurement is based on the triboelectric effect. Therefore 2 electrically isolated half-shells are arranged in a cylindric chamber (measuring cell) and are passed by the conditioned measuring air. The triboelectric signals of the sensors are converted to equivalent dust signals in the electronic of the control unit
