Field of application

Liquiline CM444R allows you to connect up to 4 Memosens sensors of your choice from over 12 measurement parameters. With its compact design, it fits into any cabinet and can be expanded at any time with inputs, outputs, controllers, math modules, and sensor channels. The transmitter belongs to the Liquiline platform with standardized system integration, operation, and spare parts. Heartbeat Technology helps you find the ideal balance between measurement point availability and maintenance costs.

Liquiline CM444R is suitable for all industries and their utilities, such as:

Food & Beverages
Life Sciences
Power & Energy
Water & Wastewater
Chemicals
Marine

It features the following communication protocols and interfaces:

0/4...20 mA
HART
PROFIBUS DP
Modbus RS485/RTU
Modbus TCP
EtherNet/IP
PROFINET
Webserver

The transmitter can be extended with a module whose explosion protection approvals, such as IECEx, ATEX, and CSA, allow the connection of sensors installed in hazardous areas.

Benefits

Saves space, saves money:
Small footprint, 4 channels in one device, expandable at any time, saves space in cabinets – perfect for skids.
High-speed installation:
No cut-out in cabinet door, one-click DIN-rail mounting, minimized wiring.
Simple and safe commissioning:
Saving configuration on SD card enables fast set-up on duplicate installations.
Easy to operate and service:
Intuitive user interface, hot plug & play with pre-calibrated Memosens sensors, universal components fit all parameters.
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.
