Dust monitor offers highly sensitive measurement

Don Horne   

GetImage51The Yokogawa model DT450G dust monitor detects the qualitative level of dust or particulate matter using the inductive electrification principle. It provides highly sensitive measurement and is capable of detecting particles as small as 0.3 µm. Utilization of inductive electrification allows for detection of not only particles which make contact with the probe, but particles which pass by the probe. The signal generated is processed by advanced noise filtering algorithms, resulting in highly accurate dust measurement. Trend level changes can be used to adjust process settings such as electrostatic precipitator charge level or to help identify filtration problems such as bag filter breakage.
