Mesure de poussières par technologie Light Scatter
DM 170
Analyseur de poussière conforme aux attentes du TÜV au regard de la norme EN 15267 pour la mesure de particules dans de nombreuses applications industrielles
Système non intrusif sans piège à lumière, adapté aux fumées sans condensation, abrasives/corrosives et chargées en poussières
S’installe d’un seul côté du conduit : facilité d’installation, diminution du risque de contamination des éléments optiques, maintenance aisée.

- ProScatter™ Backscatter sensor technology with superior minimum detection as low as 1mg/m3 compared to conventional techniques
- Manual and remote Zero and Span (Reference) checks available to ensure optimal instrument performance
- Purge Flow Fail Sensor and Optical Shield options
-
li>Offers a more reliable PM dust measurement as an alternative to Opacity and Scintillation based monitors for emissions that are reported in mg/m3 and provides
- Non-intrusive system designed to operate in noncondensing stack environments and to reduce the risk of contamination
early indication of increased dust emissions in processes with low dust concentrations
- Contamination risks are further reduced due to singleside stack installation where critical optical components remain outside the stack
- A Flue Gas Blocker can be fitted to ensure that flue gases do not escape when the unit is opened (for auditing/maintenance purposes), thus enhancing on-site personnel safety
The DM 170 is well-suited for use in medium to large stacks and is suitable for low to high dust concentration measurements, regardless of dust velocity or charge.
- Typical applications include:
- Continuous Emission Monitoring (CEM) relative to Emission Limit Values (ELV) in Power Plant, Boiler and Metal Smelting applications
- Filter performance monitoring in Metal, Mineral and Chemical plants
