Product Information Dusty
Use
The Dusty was specially developed to reliably monitor clean sides after filters for filter breaks without delay.
The Dusty can be used in metal channels in which dust particles are to be detected in flowing gas. Its operational range starts at dust volumes of 0.1 mg/m3. In systems with explosion hazard area zone 22, the "Dusty DustEx 22” type can be used. Due to its speed and reliability, the Dusty can also be used optimally as an alternative and/or expansion to the "police filter” as well as an alternative to the differential pressure measurement. The Dusty uses the electrodynamic effect. As soon as particles either flow past or impact the measuring probe, a charge transfer takes place. This generates a measuring signal that triggers a switch contact once the normal values described under "System” are exceeded.

Sensor calibration using the Dosed-Reference-Method
"The measurement result of the sensor is only as good as the reference to which it has been calibrated."
For this reason we have developed the dosed-reference-method as an alternative to isokinetic dust sampling.
The main basic idea of this is that a mass flow is dosed into the system which corresponds to a required concentration at a specific flow velocity.
