Key Features & Competitive Advantages

Future-Proof Memosens Digital Technology

Memosens ensures contactless, inductive signal transmission, eliminating moisture ingress and corrosion issues at the connector. Sensors store their own calibration and diagnostic data, enabling true "plug and measure" sensor exchange without process interruption, which drastically reduces maintenance time and costs.

Built-In Data Logger for Compliance & Diagnostics

The CM14-AAL variant includes a powerful integrated data logger—a significant advantage for audit trails, process optimization, and predictive maintenance. It automatically records measurements, alarms, and calibration events, simplifying regulatory compliance and troubleshooting.

Exceptional Operational Simplicity

The intuitive user interface with plain-text menus and clear graphics allows for quick setup and operation. The "To-Do List" feature guides users through calibration and maintenance steps, reducing training requirements and operator errors.

Robust Design for Demanding Environments

With a rugged IP66/NEMA 4X rated enclosure, the transmitter is built to withstand wet, dusty, and corrosive conditions. Its compact design allows for versatile mounting directly on a sensor or on a wall/pipe.

High Connectivity & Flexibility

With dual analog outputs and optional digital fieldbus communication, the CM14-AAL integrates seamlessly into any control architecture. Its compatibility with the entire Memosens sensor portfolio offers a single platform for multiple analytical parameters.

Enhanced Safety & Predictive Maintenance

Advanced sensor diagnostics monitor electrode condition, slope, and asymmetry, providing early warnings for required maintenance. This predictive capability prevents unexpected failures and ensures continuous, reliable measurement.

Why Choose the Liquiline CM14-AAL?

The Liquiline CM14-AAL is more than just a transmitter; it's a comprehensive digital measurement point for critical pH/ORP control. It transforms raw data into actionable intelligence, helping you optimize chemical dosing, ensure effluent quality, protect equipment from corrosion, and maintain strict process consistency. The addition of the onboard data logger makes it an ideal choice for applications requiring stringent documentation, such as in pharmaceutical, food & beverage, and environmental monitoring.
