Compact Panel Transmitter for Liquid Analysis

The Liquiline CM14 is designed as a basic one-channel transmitter for standard liquid-analysis measuring points. Instead of requiring a larger multiparameter transmitter, the CM14 provides a compact panel-mounted solution for applications where one measurement point needs to be monitored and integrated into the plant control system.

Its compact design allows installation in common control cabinet panel cut-outs, making it suitable for both new installations and equipment upgrades.

One Transmitter for Multiple Measurement Parameters

The CM14 can be configured for different types of Memosens digital sensors, including sensors for:

• 
  pH
  
• 
  ORP
  
• 
  Conductivity
  
• 
  Dissolved oxygen
  

This makes the transmitter suitable for different liquid-analysis applications while keeping the basic panel architecture consistent.

Memosens Digital Sensor Technology

The CM14 uses Memosens digital technology to connect with compatible sensors.

The Memosens hot-plug-and-play concept allows compatible sensors to be installed and configured quickly. Sensor data is transferred digitally to the transmitter, providing a practical interface between the sensor and the plant measurement system.

Simple Commissioning

The CM14 is intended for applications where straightforward commissioning is important.

Its combination of a single sensor input, compact panel construction and Memosens technology provides a relatively simple setup for standard measurement points without the additional complexity of a larger multi-channel transmitter.

Analog Outputs for Process Integration

The transmitter provides two 0/4–20 mA outputs, allowing measurement information to be transmitted to a PLC, DCS, recorder or other control-system equipment.

This provides a conventional analog interface for integrating the CM14 into existing industrial automation systems.

Relay Outputs for Monitoring Functions

The CM14 also provides two relay outputs.

These can be used for switching and monitoring functions associated with the measurement point, such as limit or alarm functions, depending on the configured application and control requirements.

Designed for Standard Industrial Applications

Endress+Hauser positions the CM14 for standard applications in Food & Beverage, Power & Energy, and Water, Wastewater & Waste industries and their utilities.

This makes the transmitter particularly suitable where a compact and uncomplicated liquid-analysis interface is required.

Panel-Mounted Installation

The CM14 is designed specifically for panel installation rather than field mounting.

The front of the transmitter has IP65 / NEMA 4X protection, while the body is rated IP20. This arrangement is suited to installation in a protected control cabinet or panel environment.

Compact Alternative for Standard Measuring Points

For applications that require only one measurement channel, the CM14 provides a more focused solution than larger multi-channel liquid-analysis transmitters.

It is particularly appropriate when the project requires one Memosens measurement point, standard signal outputs and a compact panel-mounted interface.
