Applications
The Memosens COS51E is particularly suitable for all kinds of wastewater treatment and utility applications and can measure in hazardous areas. The sensor offers high measurement accuracy; humid environments do not interfere with the measurement results, making the process safer. The COS51E uses Memosens 2.0 digital technology. A large number of calibration and process parameters are stored in the sensor, making it the perfect basis for predictive maintenance and IIoT technology. Low maintenance and long service life make the sensor extremely cost-effective.
The Memosens COS51E dissolved oxygen sensor is suitable for:
Wastewater treatment plants:
- Oxygen input control in aeration basins (O2)
- Process water treatment and monitoring
Utilities:
- O2 control in biological treatment processes
- Process water treatment and monitoring
Waterworks:
- Drinking water condition monitoring (oxygen enrichment, corrosion protection, etc.)
- Water quality monitoring of river, lake or sea water
The sensor can measure in hazardous areas (ATEX, FM, CSA).
Benefits
Wide measuring range: membrane-covered measuring principle with cathode design; the sensor is suitable for all kinds of wastewater measurement, including industrial and municipal wastewater treatment plants.
High measurement accuracy: membrane-covered three-electrode design for long-term stable measurement with low drift.
Higher plant availability: Memosens technology combined with the Liquiline transmitter enables plug & play, fast sensor commissioning and replacement.
Non-contact inductive signal transmission for high process safety.
The sensor uses Memosens 2.0 digital technology and stores calibration and process parameters, making it the perfect basis for predictive maintenance and IIoT technology.
