Product Description

Factory Original Endress+Hauser Liquiline CM442 Multiparameter Transmitter

The Endress+Hauser Liquiline CM442 Multiparameter Transmitter is a high-performance solution designed to meet the rigorous demands of industrial process monitoring. Engineered for versatility and reliability, this transmitter delivers accurate, real-time analysis of critical liquid parameters, ensuring seamless control over water quality, chemical processes, and environmental compliance. As part of Endress+Hauser's renowned Liquiline series, the CM442 combines advanced sensor integration, robust construction, and intuitive operation to support industries ranging from water treatment to pharmaceuticals, energy, and chemical manufacturing.

Advanced Multi-Parameter Measurement
The CM442 is a dual-channel transmitter optimized for simultaneous monitoring of two key parameters, such as pH, oxidation-reduction potential (ORP), conductivity, dissolved oxygen (DO), or resistivity. This flexibility makes it ideal for applications requiring precise coordination of interdependent variables, such as wastewater neutralization, boiler feedwater treatment, or chemical reaction monitoring. By consolidating measurements into a single device, the CM442 simplifies system design, reduces hardware complexity, and lowers operational costs.

Seamless Sensor Integration and Digital Communication
A standout feature of the CM442 is its compatibility with Endress+Hauser's Memosens digital sensors, which utilize inductive coupling technology to ensure stable signal transmission even in challenging environments. These sensors offer plug-and-play functionality, automatic recognition, and pre-calibration capabilities, minimizing setup time and reducing the risk of human error. The transmitter supports multiple communication protocols, including HART, Modbus RS485, and PROFIBUS, enabling seamless integration into existing control systems, SCADA networks, or distributed control systems (DCS). This adaptability ensures compatibility with both legacy and modern industrial infrastructures.

Rugged Design for Harsh Environments

User-Centric Interface and Smart Diagnostics
The CM442's backlit LCD display provides a clear, four-line text interface for real-time data visualization, alarm notifications, and status updates. Users can navigate menus effortlessly using a simple keypad, streamlining configuration and troubleshooting. Advanced diagnostic tools, such as Smart Sensor Management (SSM), continuously monitor sensor health, detect anomalies, and alert operators to calibration needs or potential failures. This predictive maintenance capability reduces downtime and extends sensor longevity. Additionally, the transmitter supports remote access via FieldCare software, allowing engineers to configure devices, analyze trends, and perform diagnostics from centralized locations.

Applications Across Industries
The CM442's versatility positions it as a critical tool in diverse sectors:

Water and Wastewater Treatment: Monitor pH and ORP levels in real-time to optimize disinfection processes, biological treatment, and effluent quality control.
Power Generation: Ensure boiler feedwater purity by measuring conductivity and dissolved oxygen, preventing scale formation and corrosion.
Pharmaceuticals: Comply with stringent regulatory requirements for high-purity water systems using precise pH and conductivity monitoring.
Chemical Processing: Track corrosive or reactive media in reactors, pipelines, and storage tanks for process safety and efficiency.
Food & Beverage: Validate clean-in-place (CIP) systems through conductivity and pH analysis, ensuring hygiene and product consistency.
Efficiency Through Data Management
For applications requiring historical data analysis, the CM442 can integrate with Endress+Hauser's Memograph R data logger, which stores measurement records for compliance reporting, trend analysis, and process optimization. This feature is particularly valuable in regulated industries where audit trails and documentation are mandatory. The transmitter's compatibility with PROFINET and EtherNet/IP protocols further enhances its role in Industry 4.0 ecosystems, enabling real-time data sharing and cloud connectivity.
