Endress+Hauser Liquiline CM444-AAM4CA3FF11BAA+NS: Expandable Four-Channel Multiparameter Transmitter

Endress+Hauser Liquiline CM444-AAM4CA3FF11BAA+NS liquid analysis transmitter

Four-channel flexibility for modern liquid-analysis systems

The Endress+Hauser Liquiline CM444-AAM4CA3FF11BAA+NS belongs to the CM444 family of modular four-wire multiparameter transmitters. It supports up to four Memosens sensors in any combination and can be extended for a wide range of water, process and utility applications.

Liquiline CM444 enables operators to standardize several analytical measuring points on one transmitter platform. Automatic sensor recognition, hot plug-and-play operation and a common user interface help reduce commissioning time. Modular inputs, outputs, relays, controllers and mathematical functions also allow the transmitter to operate cleaning systems or dosing pumps when suitably configured.

Important note about order code CM444-AAM4CA3FF11BAA+NS
The complete code identifies a configured device. Use the full code when requesting a quotation or replacement. Exact installed inputs, outputs, communication interfaces, power supply, modules and approvals must be verified from the nameplate, order documentation and current manufacturer configuration data.
