8-channel transmitter | Liquiline CM448

See this offer on the supplier's website

Flexible multiparameter field device for all industries.

Liquiline CM448 is a digital multiparameter transmitter for process monitoring and controlling in any application. The 8-channel controller saves you time and money by offering seamless system integration, simple operation and a reduced need for spare part stock.

Adapt the controller exactly to your measuring task and connect 1 to 8 sensors as desired. Liquiline CM448 provides you with all the benefits of a best-in-class transmitter platform from clever simplicity to maximum process safety.

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

• Complete package: 8 channels in one device provide the highest flexibility for every measuring task.

• Seamless system integration: Unique portfolio of communication standards suits every distributed control system (DCS).

• Simple and safe commissioning: Convenient setup multiplication to other devices with SD-Card saves time and minimizes effort.

• 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.

Liquiline CM448 features all common communication protocols and interfaces, such as:

• 0/4...20 mA

• HART

• PROFIBUS DP

• Modbus TCP / Modbus RS485

• EtherNet/IP

• Webserver
