Endress + Hauser Liquiline CM442 Channel Transmitter is an extensible multiparameter controller for monitoring and controlling processes in industry and the environmental sector.
Depending on the version ordered, up to 8 digital sensors with Memosens technology can be connected. The measuring signals can be linked by means of the mathematical function and new measured values calculated (e.g. pH calculation based on differential conductivity measurement). Furthermore, up to eight 0/4 to 20 mA analog outputs are available. Digital Fieldbuses (HART, PROFIBUS, Modbus) and
the integrated web server offer additional options for connecting to process control systems. A cleaning function, controller and alarm relay can be selected. Optional current inputs are available for processing measured values from other devices, e.g. flow or level.

Application :

Liquiline CM442 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:

• Clever simplicity:
  One controller for all parameters and applications, intuitive user interface, automatic sensor recognition, hot plug & play with pre-calibrated Memosens sensors.

• High flexibility:
  Universal modules for all parameters minimize spare part stock and allow for easy 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.
