ENDRESS+HAUSER  COS81D-AAA2CB11

Sensor with maximum measurement stability over multiple sterilization cycles

Typical applications include:

• Oxygen control in fermenters, e.g. in the pharmaceutical or biotechnology sectors
• Monitoring of explosive atmospheres with an oxygen concentration of up to 2%
• Quality control in the food industry

• Accurate measurements with longterm stability and permanent self-monitoring
• Can be sterilized up to 140 °C (284 °F) and autoclavable
• Stainless steel 1.4435 (AISI 316L) meets the highest demands of the pharmaceutical industry
• IP68 protection
• Sensor certified in accordance with EHEDG
• Complies with the relevant sections of the ASME-BPE
• Available with a certificate of conformity for pharmaceutical requirements
• Available with inspection certificate EN 10204-3.1
• Materials compliant with FDA and/or USP class VI specifications

• Maximum process safety thanks to non-contact, inductive signal transmission
• Data security thanks to digital data transmission
• Very easy to use as sensor data saved in the sensor
• Recording of sensor load data in the sensor enables predictive maintenance

Oxygen-sensitive molecules (markers) are integrated into an optically active layer (fluorescence layer).
The fluorescence layer, an optical insulating layer and a cover layer are applied on top of one another on a carrier. The cover layer is in direct contact with the medium.
The sensor optics are directed at the rear of the carrier and therefore at the fluorescence layer.

A complete measuring system comprises:

• a Memosens COS81D oxygen sensor
• Measuring cable CYK10
• A transmitter, e.g. Liquiline CM42, Liquiline CM44x/R, Liquiline CM44P, Liquiline Compact CM72/82
• Optional: an assembly, e.g. permanent installation assembly CPA442, flow assembly or retractable assembly CPA875
