Oxymax COS61D
Technical Data
CompareOxygen
| Measuring Principle | Optical oxygen measurement |
| Application | Aeration tank, river monitoring, water treatment, fish farming |
| Characteristic | Digital, optical measurement of dissolved oxygen based on fluorescence quenching Measurement possible in still water |
| Measuring range | 0 to 20 mg/l 0 to 200 %SAT 0 to 400 hPa |
| Measuring principle | Oxygen-sensitive molecules (marker) are integrated in an optical active layer (fluorescence layer). The fluorescence layer surface is in contact with the medium. The sensor optics are directed at the back of the fluorescence layer. The sensor optics transmit green light pulses to the fluorescence layer. The markers respond (fluoresce) with red light pulses. The duration and intensity of the response signals depend directly on the oxygen contents or partial pressure. |
| Design | Calibration data saved in sensor High degree of EMC protection |
| Material | Sensor shaft: stainless steel 1.4571 Membrane cap: POM |
| Dimension | Diameter: 40 mm (1.57 inch) Shaft length: 186 mm (7.32 inch) |
| Process temperature | -5 to 60 °C (20 to 140 °F) |
| Process pressure | Max. 10 bar abs (Max. 145 psi) |
| Temperature sensor | NTC 30K |
| Connection | Process connection: G1, NPT 3/4" Cable connection: fixed cable or TOP68 plug-in-head |
The Oxymax COS61D is a high-performance digital dissolved oxygen sensor that provides fast, precise and drift-free measurement, with low maintenance, high suitability and simple operation. The long-term stable fluorescence layer of the sensor is oxygen-selective (interference-free), ensuring always reliable measurement. Using Memosens digital technology, the Oxymax COS61D also offers maximum process and data integrity and is easy to operate. Laboratory calibration and device predictive maintenance are possible.
