A Universal Transmitter for Multiparameter Liquid Analysis
The CM44P is designed for applications where several liquid-analysis measurements need to be managed through a single transmitter. Its architecture combines process photometers with Memosens sensors, allowing users to build a measurement system around different analytical requirements.
Rather than being limited to one measurement principle, the CM44P provides a common platform for integrating optical and digital sensor technologies into the same process-analysis system.
Designed for Process Photometers and Memosens Sensors
One of the defining characteristics of the CM44P is its ability to combine process photometers with Memosens sensors.
Depending on the configuration, the transmitter can accommodate one or two process photometers and up to four Memosens inputs. This makes it suitable for installations where optical analysis needs to be combined with parameters such as pH, ORP, conductivity or oxygen.
Supports a Broad Range of Measurement Parameters
The CM44P can be configured for different liquid-analysis parameters depending on the connected sensors and selected options.
Compatible measurement technologies include Memosens sensors for parameters such as pH, ORP, conductivity and dissolved oxygen, while process photometers provide optical measurement capabilities for applicable analytical applications.
This flexibility allows the same transmitter platform to be used across different process-monitoring requirements.
Flexible Installation for Field or Cabinet Applications
The CM44P is available in different housing arrangements. The transmitter can be installed as a field device or without the field housing for DIN-rail installation in control cabinets.
This makes it suitable for both decentralized measuring points close to the process and centralized instrumentation cabinets.
Multiple Outputs for Process Integration
The CM44P provides flexible output options for connecting the measurement system to plant control and monitoring equipment.
Depending on configuration, the transmitter supports 2 to 8 current outputs, together with alarm and relay functions. The official product information also lists up to four relays.
This allows measured values and process-status information to be integrated into existing automation systems.
Practical Data and Configuration Management
The CM44P includes an SD card interface that can be used for software updates and for copying and pasting device settings. This can simplify configuration management when multiple transmitters or similar measuring points are installed.
Designed for Easy Operation
Ease of use is an important part of the CM44P platform. The transmitter provides a common operating concept for its connected sensors and measurement technologies, helping operators manage different analytical parameters from a centralized interface.
This is particularly useful for installations where several measurements are handled by the same process-analysis system.
Suitable for Complex Process Monitoring
The CM44P is intended for applications where a simple single-channel transmitter is not sufficient. Its combination of multiple Memosens inputs, process photometer integration and expandable output options makes it suitable for more complex liquid-analysis installations.

FAQ
What is the Endress+Hauser Liquiline CM44P?
The CM44P is a multichannel transmitter for process photometers and Memosens sensors. It provides a common platform for combining optical and digital liquid-analysis measurements.
How many sensors can the CM44P connect?
Depending on the configuration, the CM44P supports up to four Memosens inputs and can also accommodate one or two process photometers.
Is the CM44P a sensor?
No. The CM44P is a transmitter. The actual measurement is performed by the connected Memosens sensors and process photometers.
What parameters can the CM44P measure?
Depending on the selected sensors and configuration, the CM44P can support parameters such as pH, ORP, conductivity and dissolved oxygen, together with analytical measurements performed by compatible process photometers.
Can the CM44P be installed in a control cabinet?
Yes. Endress+Hauser offers the CM44P without the field housing for DIN-rail installation in cabinets. A field-device version is also available.
Does the CM44P support Memosens sensors?
Yes. Memosens is one of the two main measurement technologies supported by the CM44P, alongside compatible process photometers.
How many process photometers can be connected?
