Multichannel Transmitter Models

Endress+Hauser introduced the Liquiline CM44 Series, multichannel transmitter models 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, 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 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. (
