Memosens digital sensor technology for liquid analysis
(mp4 format, 61.7 MB)
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.Animation11/15fr -
Memosens digital sensor technology for liquid analysis
(mp4 format, 61.7 MB)
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.Animation11/15fr -
