Compact multiparameter DIN-rail and cabinet device for all industries
Field of application
Liquiline CM442R allows you to connect up to 2 Memosens sensors of your choice from over 12 measurement parameters. With its extremely compact design, it fits into any cabinet - and even offers inputs, outputs, controllers, and math modules, e.g. for cleaning control. 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 CM442R is suitable for all industries and their utilities, such as:
Food & Beverages
Life Sciences
Power & Energy
Water & Wastewater
Chemicals
Marine
0/4...20 mA
HART
PROFIBUS DP
Modbus RS485/RTU
Modbus TCP
EtherNet/IP
PROFINET
Webserver
Benefits
Saves space, saves money: Extremely small footprint, 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.
