D-R 320
For continuous, contactless measurement of low to medium dust concentrations in dry flue and process gases. Also suitable for corrosive gases and potentially explosive atmospheres.
- Principle: Backscattering of a red laser diode by dust particles
- Installation: Single-sided, in-situ, contactless; easy setup on standard flanges (DN100/4″) without light traps or adjustments
- Measurement: Continuous monitoring of small to medium dust concentrations (e.g., down to 0–7.5 mg/m³)
- Automation: Automatic zero point, reference point, and contamination checks; integrated purge air monitoring
- Reliability: Long service intervals; optional fail-safe shutter; compliant with EN 15267
- Operation: Remote access possible; simple operation via optional units (D-ISC 100)
- Incineration Plants: Monitoring emissions from municipal, hazardous, and sewage sludge waste incineration.
- Power Plants: Used in gas, oil, coal, and co-firing power stations.
- Cement Manufacturing: Dust monitoring in cement production facilities.
- Biomass Incineration: Emission monitoring in biomass incineration plants.
- Refineries & Steel Industry: Suitable for emission and process monitoring in steel plants and refineries.
