De sensor is ontworpen volgens ASME BPE en EHEDG en is geschikt voor toepassingen met de hoogste hygiënische eisen, zoals fermentatie, inertisatie of drinkwaterproductie.
Memosens COS81D met c-vormige tip van de sensorkap. Gebruik deze kap voor zuurstofmetingen in vloeistoffen zoals fermentortoepassingen om de aanhechting van luchtbellen te voorkomen.
Memosens COS81D met u-vormige tip van de sensorkap. Gebruik deze kap voor zuurstofmetingen in gasfasen zoals voor inertisaties, waarbij abrasieve deeltjes de optische laag van de kap zouden kunnen beschadigen.

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.
