Gravimetric dust measuring device
Filter controller Dust measuring devices
Measuring principle The GMD 06 is an automatic sampling device for gravimetric dust measurements. These measurements are used as reference measuring method for the calibration of dust measuring devices (in Germany according to DIN VDI 2066). Furthermore it is possible to measure flow. The GMD 06 is able to determine independently all exhaust gas parameters being necessary for the dust measurement (e.g. humidity of the measuring gas, velocity in the stack as well as temperature and pressure). Under consideration of these parameters the GMD 06 extracts automatically a partial gas flow in isocinetic way from the exhaust gas channel. This partial gas flow is sucked via a filter, in which the dust contained is precipitated. A f t e r t h e measurement the filter is treated and weighed. When the filter mass weighed out has been entered manually, the GMD 06 calculates the dust content of the sample in operation and norm state.
Technical data control unit
The manual one For the gravimetric determination of the dust concentration Application: Measurement 1
of the absolute exhaust gas humidity Measurement of the 1 exhaust gas velocity (and D p, temperature) Measurement of the 1 exhaust gas content semi-automatic 1 calculation of the dust concentration after the determined dust mass has been entered
