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
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
