Endress Hauser Digital oxygen sensor Oxymax COS61D-AAA1A3

SPECIFICATIONS

• 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

• Measurement 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 1.4435；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

Field of application

Oxymax COS61D is a high-performance, digital oxygen sensor that offers fast, accurate and drift-free measurement. It supports your process with low maintenance, high availability and easy handling. The sensor's long-term stable fluorescence layer is exclusively oxygen-selective (interference-free), ensuring consistently reliable measurement. Thanks to Memosens digital technology, the Oxymax COS61D combines maximum process and data integrity, and facilitates simple lab calibration.
