The conductivity of a liquid can be measured using the conductive or toroidal 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.
Condumax CLS21D is a robust conductivity sensor for all process and environmental applications. It provides you with precise and reliable measuring values for an optimum process and product quality monitoring. Better still, the sensor features high chemical, thermal and mechanical stability and high durability. Thanks to Memosens digital technology, CLS21D combines maximum process and data integrity with simple operation. It resists corrosion and moisture and facilitates predictive maintenance.

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 converts the measured value to a digital signal and transfers
it to the transmitter without a contacting connection.
This video shows how it works and how people in process analytics
profit from it.
