Endress Hauser 4-channel transmitter Liquiline CM444 CM444R
The Liquiline CM444 and CM444R are digital multichannel multiparameter transmitters from Endress+Hauser, designed for process monitoring and control across all industries. The CM444 features a robust field housing, while the CM444R is a DIN-rail mountable version optimized for cabinet installation in space-constrained applications.
Key Features and Benefits
-
Expandable Multichannel Architecture: The CM444 supports up to 4 digital Memosens sensor channels, with the ability to connect any combination of pH, ORP, conductivity (inductive and conductive), dissolved oxygen, chlorine, turbidity, nitrate, and ISFET sensors. Functionality is modularly extendable at any time with additional inputs, outputs, controllers, and math modules.
-
Clever Simplicity: One controller handles all parameters and applications with an intuitive user interface, automatic sensor recognition, and hot plug & play capability with pre-calibrated Memosens sensors. Configuration can be saved on an SD card for fast setup on duplicate installations.
-
Seamless System Integration: A unique portfolio of communication standards suits every distributed control system (DCS), including 0/4…20 mA, HART, PROFIBUS DP, Modbus RS485/TCP, EtherNet/IP, and PROFINET. An integrated web server allows remote viewing of diagnostic data, configurations, and device parameters via any web browser, even on smartphones.
-
DIN-Rail Convenience (CM444R): The CM444R features a compact DIN-rail design that saves cabinet space, requires no cut-out in the cabinet door, and enables one-click mounting with minimized wiring. It is ideal for skids and space-constrained installations.
-
Higher Availability, Lower Costs: Heartbeat Technology enables status-oriented maintenance and easy verification of the entire measuring point, helping to optimize maintenance efforts and maximize plant availability.
