In the field of immission measurement, cheap and compact low-cost PM-sensors have been established for monitoring particle concentration with high temporal and spatial resolution. The accuracy of these sensors is subject to many environmental influences, such as varying aerosol properties, particle concentration or relative humidity.

Another possible application for low-cost PM-sensors could be the emission measurement for industrial dust separation, like pulse-jet cleaned filter bags. Several filter bags could be equipped with low-cost sensors to investigate the contribution of individual filter bags to the total emission. The suitability of the sensors is still subject of research. The behavior during the filtration process in a VDI test rig for filter media has been investigated for the two low cost sensors OPC-N2 from the supplier Alphasense and PMS7003 from the supplier Plantower. A Welas 2100 sensor from the supplier Palas serves as a reference for the experiements.

The sensors are able to...
