Endress+Hauser Liquiline CM444 Multi-Channel Digital Field Transmitter

Advanced Multi-Channel Liquid Analysis for Industrial Processes

The Endress+Hauser Liquiline CM444 is a robust, 4-channel digital field transmitter designed to handle demanding liquid analysis applications in non-hazardous environments. Engineered for maximum operational uptime and flexibility, the CM444 acts as a centralized process controller capable of monitoring up to four Memosens digital sensors simultaneously. Whether measuring pH, ORP, conductive or inductive conductivity, dissolved oxygen, turbidity, or nitrate, the CM444 delivers continuous, highly accurate process data required for efficient process control and quality assurance.

Cutting-Edge Memosens Digital Sensor Integration

A core advantage of the Liquiline CM444 transmitter lies in its native support for Memosens digital sensor technology. Non-contact inductive signal transmission eliminates sensor failure caused by ambient moisture, corrosion, and dirt build-up. Because calibration data and process history are stored directly within the smart sensor head, maintenance teams can calibrate sensors off-site in laboratory conditions. Upon connecting a sensor to the CM444, the transmitter automatically recognizes the sensor parameters and loads calibration metrics, reducing field commissioning time to seconds.

Modular Flexibility and Future-Proof Expansion

Designed with a modular architecture, the Liquiline CM444 transmitter adapts effortlessly to expanding plant requirements. Plant operators can configure the device with up to 8 current outputs (0/4 to 20 mA), alarm relays, and digital inputs, or integrate specialized software functions such as cleaning control, dosing pumps, and mathematical modules. The rugged plastic housing (PC-FR) carries an IP66/IP67 ingress protection rating, protecting internal electronics from harsh weather, high humidity, and aggressive washdown procedures.

Seamless Automation System Integration and Connectivity

The CM444 transmitter bridges field measurement with plant-wide automation systems by offering extensive fieldbus and industrial Ethernet interfaces, including HART, PROFIBUS DP, Modbus RS485, Modbus TCP, and EtherNet/IP. Built-in web server functionality enables remote process monitoring, device configuration, and diagnostic evaluation from any standard web browser or mobile device. Additionally, integrated Heartbeat Technology provides continuous verification and self-diagnostics without process interruption, optimizing maintenance cycles and reducing total cost of ownership.
