Máy đo nồng độ bụi DURAG D-R 290
Giá:Liên Hệ
Suitability tested and certified optical transmission monitor to measure the opacity or dust concentration in dry flue gas.
OVERVIEW
- Continuous and contactless measurement
- Automatic zero and span check
- Automatic measurement and correction of contamination of optical surfaces
- Extremely powerful and stable super-wide band diode (SWBD) light source
- Extremely low-maintenance
- Fail-safe shutters with purge air monitoring as option
- Certified according to EN 15267-3
- Compliant with US EPA 40 CFR 60 PS1 and ASTM 6216
MEASURING PRINCIPLE
The D-R 290 operates using the double-pass method according to the auto-collimation principle. The light beam traverses the measuring path twice. The attenuation of the light beam caused by the dust content in the measuring path is measured and evaluated.
YOUR BENEFIT
- Certified for official emission monitoring
Type approved according to EN 15267-3, compliant with the requirements of US-EPA PS-1 and ASTM 6216 - Easy set-up for opacity monitoring
No gravimetric calibration needed when using transmission principle for reliable opacity monitoring - Broad functional range due to dual-path transmission principle
The sensitivity scales up with growing duct diameter. This allows for measuring very low dust concentrations in very big stack diameters and vice versa very high dust concentrations in small stack diameters - Suitable for harsh flue gas conditions
Non-contact measurement with purge air cushion technology allows for very high flue gas temperatures and aggressive flue gases - Durable through options purge air monitoring and fail safe shutter
Protection of the device through continuously monitored purge air supply and automatic closure of fail safe shutter in case of purge air failure - Rugged design for harsh environmental conditions
Suitable for a wide range of application due to heavy duty metal housing, a broad ambient temperature range and optional versions for EX environments - Reliable emission monitoring
Automatic control functions ensure reliable measuring values
