Field of application
Liquiline CM44P allows you to connect 2 process photometers with up to 4 Memosens sensors of your choice. It facilitates the setup of complete measuring points for monitoring processes such as
chromatography, fermentation, phase separation and filtration. Moreover, 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 CM44P is especially suited for applications in the following industries:
Life Sciences
Food & Beverages
Chemicals
Oil & Gas
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
Intelligent design: One controller for all parameters including process photometers
Cost-saving and comfortable set-up of measuring points: Combine up to two process photometers and four Memosens sensors for a perfect fit to your application
Easy to operate and calibrate thanks to intuitive user interface and menu guidance
Process control and safety: 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.
Available as DIN-rail version for applications with limited mounting space - perfect for system integrators and skids
Heartbeat Technology enables status-oriented maintenance and easy verification of the entire measuring point and helps to carry out optimization measures.
