Endress+Hauser CM442

Liquiline CM442 Controller, ENDRESS HAUSSER - IND27827-OC - 063

Liquiline CM442 is a state-of-the-art transmitter for measuring parameters such as pH, redox, conductivity, oxygen, chlorine, turbidity, sludge level, COD, nitrate, etc.

The Liquiline CM442 transmitter allows you to connect up to 2 Memosens sensors of your choice from more than 12 measurement parameters. It automatically recognizes the sensors, is easy to operate, and features standardized spare parts that are compatible with other devices in the Liquiline platform. With its inputs, outputs, controllers, and mathematical modules, you can even control cleaning systems and dosing pumps. Heartbeat Technology helps to find the ideal balance between the availability of the measurement point and maintenance costs.

Liquiline CM442 is suitable for all industries and their auxiliary applications, such as:
Food and beverage
Life sciences
Power plants and energy
Water, wastewater, and waste
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
Web server

The transmitter can be expanded with a module whose approvals for explosion protection, such as IECEx, ATEX, and CSA, allow it to be connected to sensors installed in areas with a risk of explosion.

Advantages
Intelligent Simplicity:
one controller for all parameters and applications, with an intuitive user interface, automatic sensor recognition, and plug & play hot-swapping with pre-calibrated Memosens sensors.

High Flexibility:
universal modules for all parameters minimize spare parts inventory and allow the system to be expanded at any time with up to 8 channels.

Direct Integration into the System:
the unique portfolio of communication standards adapts to any distributed control system (DCS).

Simple and Safe Commissioning:
the ability to save the configuration to an SD card allows for quick commissioning of duplicated installations.

Remote Process Control:
integrated web server that allows the operator to remotely view diagnostic data, perform configurations, or access the equipment parameters from any web browser, even from a smartphone.

Higher Availability, Lower Costs:
Heartbeat Technology enables condition-based maintenance and simple verification of the complete measurement point, in addition to helping you take optimization measures.

Promoting Connectivity: Liquiline Edge Module CYY7 transfers process data to Netilion, regardless of the fieldbus. This allows for an overview and the use of IIoT services. It is available in new products or as an upgrade for installed Liquiline platforms.
