Endress+Hauser Liquiline CM448-AA36A31AABAA+AA: High-Capacity Eight-Channel Multiparameter Transmitter

Endress+Hauser Liquiline CM448-AA36A31AABAA+AA liquid analysis transmitter

Eight-channel capacity for complex liquid-analysis systems

The Endress+Hauser Liquiline CM448-AA36A31AABAA+AA belongs to the CM448 family of modular four-wire multiparameter transmitters. The platform can connect up to eight digital Memosens sensors, making it well suited to plants that need several analytical parameters, extensive I/O and flexible communication in one field device.

Liquiline CM448 gives operators a consistent interface for multiple measuring points. Memosens hot plug-and-play, automatic sensor recognition and the use of laboratory-calibrated sensors help simplify commissioning and maintenance. Its modular design also allows functions such as outputs, relays, controllers, cleaning programs and digital communication to be adapted to the application.

Important note about order code CM448-AA36A31AABAA+AA
The complete code identifies a configured device. Use the full code when requesting a quotation or replacement. Exact installed sensor channels, inputs, outputs, relays, communication interfaces, power supply, modules and approvals must be verified from the nameplate, order documentation and current manufacturer configuration data.
