Filter-Guard 206 Dust Filter Monitoring Application The ADOS Filter-Guard 206 in combination with an evaluation unit continuously monitors the clean air side of any fine dust filter installation. A warning is initiated when a sudden increase in dust concentration is present, i.e. due to a breakdown in the filter casing or bag. Measurement range is 0–100 % dust. Measurement range value – total dust: 0,1 – 20 mg/m3 0,1 – 50 mg/m3 0,1 – 100 mg/m3 Fields of Application Monitoring fine dust filter systems at the clean air side Vibrating and jet filter systems Air extraction installations in wood and plastic processing plants Air conditioning units with dust filter systems Paint and varnish production Ambient air monitoring at workplaces and many more Features Suitable for various types of dust 4-20mA standard output signal LON® interface (optional) Low current consumption Robust aluminium housing Straightforward installation Easy exchange of the sensor elements Detectable Types of Dust Dry dusts: Wood dust Household dust Colouring pigments Plastic dust Flour dust Metallic dust Mineral dust and many more Evaluation Units Multi-channel installations: MWS 897 MWS 903 LON®-Center 2000 GW 399 Multitronik MC 602 Technical Data Measurement principle: optical light dispersion Fields of application: filtermonitoring for dry, not sticking, not lumping, not hygroscopic substances Measurement ranges: 0 – 100 % dust approx. measurement range: total dust 0,1 – 20 mg/m3 0,1 – 50 mg/m3 0,1 – 100 mg/m3 dependant on the kind of dust at the measuring point Medium humidity: dry Measurement accuracy: pure warning function, no metering unit Ambient temperature: -10 °C to +50 °C Response time (t90): < 10 s Installation: flexible flange for output air channel construction (flat and round channels) Protection class: IP 54 Output signals: analog output 4 (0)–20 mA RS 485 / LON® Voltage supply: 24 V= Power consumption: 3 VA Dimensions (D x L): 50 x 300 mm or 50 x 600 mm (long version) Weight: approx. 0,95 kg Trademark right: EU-patent Accessories Signal horns, warning lamps, warning banners, air control accessories, metering units, plotters, data-logger.
