DURAG D-R 290
General Details
Optical Dust and Opacity Monitor
Certified optical transmission analyzer to measure the opacity or dust concentration of sample gas. Suitable for plants which require the monitoring of dust missions by law.
Suitable for dust concentration measurement:
- at incinerators in general
- at garbage, hazardous waste and sewage sludge incinerators,
- at facilities for cement production
- at power stations with gas, oil, coal or co-firing
Suitable for measuring the opacity in the exhaust gas:
- at incinerators in general
Suitable for monitoring of filter facilities
Suitable for measurement of dust load in warehouses.
Overview
- Suitable for systems with variable gas speed
- Allows calibration to measure the dust concentration in mg/m3
- Measures opacity and/or optical density
- Can be used even at thick-walled stone / insulated ducts
- Device is not in contact with sample gas
- Automatic zero and reference point check
- Automatic measurement and correction of soiling of optical windows
- Super-wide band diode (SWBD), long life, reduced influence of variable particle sizes
- Hermetically sealed enclosures – no flue gas diffusion to optics or electronics unit
- Optimized purge air reduces pollution, provides long maintenance intervals
- Heated optical window
- Easy installation, adjustment and maintenance, no PC required
- Local control unit displays opacity, extinction or mg/m3 values
- Additional display unit as an option in up to 1000m distance
- Automatic range switching output
