Product Description

Overview Specifications Models Delivery Information Manuals + Resources

The Liquiline CM444 is a highly versatile 4-channel transmitter suitable for all industries and their utilities—including Food & Beverages, Life Sciences, Power & Energy, Water & Wastewater, Chemicals, and Marine—designed to connect up to 4 Memosens sensors across over 12 measurement parameters, with features like automatic sensor recognition, flexible expandability, and standardized spare parts aligned with the Liquiline platform.

Boasting robust specs, it offers 1 to 4x Memosens digital inputs (plus optional 2x 0/4 to 20mA inputs and 2 to 4x digital inputs) and diverse outputs/communication capabilities: 2 to 8x 0/4 to 20mA current outputs, alarm relay, 4x relay, and support for protocols including Profibus DP, Modbus RS485, Modbus TCP, Ethernet, HART, EtherNet/IP, PROFINET, alongside a built-in webserver; its ingress protection of IP66/IP67 ensures durability in harsh environments, and it can be extended with a module for connecting sensors in hazardous areas (backed by IECEx, ATEX, CSA approvals).

Clever Simplicity

One controller for all parameters, intuitive interface, hot plug-and-play with pre-calibrated Memosens sensors.

Highest Flexibility

Universal modules reducing spare parts and 1-click expansion to 8 channels.

Seamless Integration

Comprehensive communication standards suitable for any DCS configuration.

Safe Commissioning
