Endress+Hauser introduces the Liquiline CM44 Series multichannel transmitter for monitoring and controlling processes in water & wastewater, chemical, power and other industries. CM44 models accept inputs from up to eight Endress+Hauser Memosens digital analytical sensors including nitrate, spectral absorption coefficient (SAC), pH, ORP, conductivity, oxygen, turbidity and ion selective electrode sensors. Memosens sensors are lab-calibrated devices that simply plug into the CM44 via an M12 connector. The CM44 can be field-upgraded from two to four or four to eight sensors simply by plugging in new modules. Optional current inputs are available for processing signals from other process devices such as flow, level or pressure sensors. Outputs from the CM44 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 CM44’s Ethernet TCP port. Using any Web browser, users can perform remote configuration or access to device parameters.
