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
