  • Very easy to use as sensor data saved in the sensor
  • Recording of sensor load data in the sensor enables predictive maintenance
Measuring principle Sensor structure

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.

Measuring system

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

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
