4-channel transmitter Liquiline CM444

Brand: Endress+Hauser Group Services AG

The Liquiline CM444 transmitter allows you to connect up to 4 Memosens sensors of your choice from over 12 measurement parameters. It offers automatic sensor recognition, flexible expandability, and standardized spare parts with all other devices of the Liquiline platform. With its inputs, outputs, controllers, and math modules, you can even control cleaning systems or dosing pumps. Heartbeat Technology helps you find the ideal balance between measuring point availability and maintenance costs.Features
  • Clever simplicity:One controller for all parameters and applications, intuitive user interface, automatic sensor recognition, hot plug & play with pre-calibrated Memosens sensors.
  • Highest flexibility:Universal modules for all parameters minimize spare part stock and allow for easy 1-click extension to up to 8 channels at any time.
  • Seamless system integration:Unique portfolio of communication standards suits every distributed control system (DCS).
  • Simple and safe commissioning:Saving configuration on SD card enables fast set-up on duplicate installations.
  • Process control from a distance:Integrated web server that allows the operator to remotely view diagnostic data, perform configurations, or access device parameters in any web browser - even via Smartphone.
  • Higher availability, lower costs:Heartbeat Technology enables status-oriented maintenance and easy verification of the entire measuring point and helps to carry out optimization measures.
  • Drive connectivity:Liquiline Edge Module CYY7transfers process data to Netilion, independently of the fieldbus. This allows remote overview and the use of IIoT services. It’s available in new products or as upgrade to installed Liquiline platforms.
