GMD 06
PRODUCT INFORMATION 3
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.

Dust measuring device
Measuring principle Function:
If 2 solid bodies get into contact by friction or touching, an electrical charge transfer will be caused. The arising charge difference is the base for triboelectric filter controllers and dust measuring devices which use the charge exchange between measuring probe and nearby streaming or direct impacting dust particles. Auswerteeinheit Staubsensor The triboelectric signal depends on the mechanical and electrical properties of the dust. Apart from the dust concentration it seems that the gas velocity has the biggest influence on the triboelectric charge transfer.
General advantages: In-situ online measurement of the dust content 1 High measuring accuracy 1 simple assembly without special tools 1 low demand for maintenance (long operating times) 1 no influence of probe pollution on the measuring 1 result no purging air required 1 low operating costs 1

Selection of measuring point In order to get representative results with regard to the dust concentration of plants, whose emissions have to be monitored continuously, the correct installation of the dust measuring devices is a basic pre-condition. This is also valid for the application of measuring devices within the frame of process monitoring (e.g. qualitative measurement - monitoring of the clean gas dust content of bag filters). The installation point of the probe should fulfil the requirements of local valid guidelines (e.g. EN 132841, VDI 2066 page 1). In case of doubts it is recommended to let determine the measuring point by a responsible measuring institute (in Germany according to §§ 26/28 BImSchG). We recommend to realise at least 5 times the diameter of the exhaust gas channel as entry and exit section.

PRODUCT INFORMATION 3
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
