DURAG D-R 220
General Details
Optical Dust and Opacity Monitor
Optical optical transmission analyzer to monitor the opacity or dust concentration in combustion and filter systems, ducts and warehouses.
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
- Replaces D-R 216
- In-situ measurement, continuous operation
- Suitable for applications with variable gas speed
- Allows calibration to measure the dust concentration
- Measurement of opacity
- Qualitative dust measurements for monitoring the function of filters
- Also used in thick-walled stone / insulated ducts
- Device is not in contact with sample gas
- Long-life LED
- Hermetically sealed housing – no flue gas inlet in optics or electronics unit
- Easy installation, adjustment and maintenance
- Parameterization is possible with or without a PC locally
- Parameterization from external via RS-485 Modbus RTU possible
