The concentration of oxygen dissolved in a liquid can be measured using the amperometric or optical measuring principles. This video shows what it is about and how these measuring principles work.
Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
Oxymax COS51D is a reliable and highly accurate oxygen sensor for all kinds of water & wastewater applications (including hazardous areas). Designed to be low-maintenance with a long operating life, the sensor offers outstanding value for money. Thanks to Memosens digital technology, the Oxymax COS51D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.

Digitale Sauerstoffsonde mit Memosens-Technologie
zur Bestimmung von gelöstem Sauerstoff in wässriger Lösung nach dem
amperometrischen
Messprinzip
De Memosens technologie van Endress+Hauser is een revolutie in
vloeistofanalyse.
Het zet een analoge meetwaarde om in een digitaal signaal dat geheel
galvanisch
gescheiden naar de transmitter gaat.
Memosens sensoren slaan kalibratie-, sensor- en procesdata op in hun
interne
geheugen. Dit zorgt voor een juiste processturing en optimaal onderhoud.
La technologie Memosens Endress et Hauser révolutionne l'analyse
physico-
chimique. Elle convertit les valeurs mesurées en signaux numériques et
les transfère
au transmetteur via une connexion sans contact.
Les capteurs Memosens mémorisent les données d'étalonnage, de capteur et
de
process, ce qui permet un contrôle précis du process et une maintenance
optimale.
Memosens digitalisiert den Messwert im Sensor und überträgt ihn
kontaktlos zum Messumformer.
Dieses Video zeigt, wie Memosens funktioniert und wie PAT-Mitarbeiter
davon profitieren.
