How it works
Multi‑parameter Field Instrument
Key features
• Supports the following communication protocols and interfaces: 0/4...20 mA, HART, PROFIBUS DP, Modbus, Ether Net/IP, PROFINET, Webserver
• The transmitter supports functional expansion. When fitted with IECEx, ATEX and CSA explosion‑proof modules, it can connect sensors for use in hazardous areas.
• Simple and smart: one controller meets measurement requirements for various parameters and diverse applications. It features an intuitive user interface, automatic sensor recognition, and plug‑and‑play operation with pre‑calibrated Memosens digital sensors.
• High flexibility: universal modules for all parameter measurements reduce spare‑parts inventory. The system can be easily expanded to an 8‑channel measurement system at any time.
• Seamless system integration: unique combination of standard communication methods compatible with different types of Distributed Control Systems (DCS).
• Simple and safe commissioning: instrument configurations are stored on an SD card for fast setup during repeated installations.
• Remote process control: built‑in web server allows operators to view diagnostic data remotely, perform instrument configuration, or access device parameters via any web browser — even on a smartphone.
• Higher availability with lower operating costs: featuring Heartbeat Technology for condition‑based maintenance scheduling. On‑site verification can be performed effortlessly at measuring points to support targeted optimisation actions.
• Connectivity capability: process data is uploaded to the Netilion IIoT cloud ecosystem via the Liquiline Edge Module CYY7, independent of any fieldbus. It enables remote viewing and access to IIoT digital services. The edge device is available as an option for new units and can also be retrofitted to Liquiline platform products.
Typical applications
The Liquiline CM442 transmitter can connect up to 2 Memosens digital sensors, with flexible selection from as many as 12 measurement parameters. It features automatic sensor recognition and easy operation, and uses standardised spare parts consistent with all other Liquiline platform products. Equipped with input, output, controller and arithmetic calculation modules, it can control cleaning systems or feed pumps. Featuring Heartbeat Technology, it helps users strike an optimal balance between measuring‑point availability and maintenance costs.
The Liquiline CM442 transmitter is suitable for applications across all industries and their utility systems, including: food & beverage, life sciences, power & energy, water & wastewater, chemical, marine engineering.
