Endress+Hauser's Liquiline CM444 and CM448 transmitters accept inputs from up to eight sensors

Endress+Hauser's Liquiline CM444 and CM448 multichannel transmitters are designed for monitoring and controlling processes.

Liquiline CM444 and CM448 accept inputs from up to eight Endress+Hauser Memosens digital sensors including nitrate, spectral absorption coefficient (SAC), pH, ORP, conductivity, dissolved oxygen, turbidity, free-chlorine and ion selective electrode sensors. The device is made to recognize any combination of Memosens sensors and starts operating immediately. Memosens technology means all sensors can be precalibrated in the laboratory. When connected to the Liquiline series of transmitters, sensors are recognized automatically.

Outputs from the CM444 and CM448 transmitters include up to eight 4-20mA current outputs with HART; as well as Ethernet, Profibus, and Modbus TCP or 485 networks. An integrated Web server provides remote access via any web browser.

Additional outputs include up to four relay outputs capable of switching 24, 115 or 230VAC. The relay outputs can be used to sound alarms, start or stop cleaning functions, activate a controller, or perform other related functions. 

The web server connects to the Internet via the CM444 or CM448 transmitter’s Ethernet TCP port. Using any web browser, users can perform remote configuration or access to device parameters.
