Different Ethernet and Fieldbus modules enable digital communication and seamless integration into automation systems.
Wide Sensor Selection
Protos II 4400 (X) is the only process analysis system that can be flexibly combined with Memosens and other digital or analog sensors — in multi-channel mode as well.
With Memosens technology, up to 6 measuring channels can be imple-mented in parallel.
Status Messages acc. to NE 107
All status messages for maintenance requests, failure, out of specification, and function check (HOLD) are output as specified in NE 107.
Reliable and Safe Thanks to Memosens Technology
Digital sensors with inductive signal transmission — contactless sensor couplings ensure the reliable analysis of liquid in all environments. Sensors that are pre-calibrated in the laboratory deliver maximum availability and reduced maintenance efforts at the point of measurement. Even for non-specialist employees, sensors can be replaced on site in just a matter of seconds.
