Gravimetric dust measuring devices

Portable Gravimetric dust measuring device

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.

• Nearly no dust loss due to optimized sampling system
• Automatic data recording and system control
• Isokinetic control in real time
• Automatic storage and evaluation of the measuring values
• Automatic measurement of the flow angle and detection of swirl effects

Benefits

• High measurement accuracy even at low dust concentrations
• Measurement results are available immediately after sampling
• Due to the compact design and low number of components, only one person is necessary for transport and operation
• Fields of applications
• Calibration of continuous dust measuring devices
• Acceptance test measurements in filter systems
• Occasional check measurements
• Flow and temperature profile measurements, determination of the flow direction
