Gravimetric dust measurement devices extract a partial gas flow from the duct under predefined conditions and use a filter to separate out the dust particles. The amount of dust is ascertained by weighing the filter. The differential pressure is measured to determine the extracted volume. These two values are then used to calculate the concentration of dust in the duct with a high level of accuracy. Gravimetric dust measurement is ideal for calibrating other dust measuring devices and for taking the kinds of comparative measurements that are required by the relevant authorities.
The SHC500 Gravimat is used for gravimetric measurements for the calibration of dust monitors and for comparison measurements in filter systems. A partial gas flow is extracted isokinetically via a filter head probe. The extraction process is controlled automatically and in real time. The dust content is determined by weighing the dust collector mass before and after extraction.
