Flexible Transmitter for Multiple Liquid Analysis Parameters
The Endress+Hauser Liquiline CM42B is a modular two-wire transmitter designed for a wide range of liquid analysis applications. It can be configured for measurement of pH, ORP (Redox), conductivity or dissolved oxygen, providing a flexible solution for different process requirements.
Unlike dedicated single-parameter transmitters, the CM42B allows users to standardize their instrumentation platform across multiple measuring points, reducing engineering effort and simplifying spare parts management.
Typical applications include:
Chemical process monitoring
Pharmaceutical production
Food and beverage processing
Water treatment
Power and energy systems
Hazardous area applications
Memosens Digital Technology and Analog Sensor Support
The CM42B supports Memosens digital sensor technology, allowing secure transmission of measurement data from the sensor to the transmitter.
Memosens technology provides advantages such as:
Digital signal transmission
Reduced influence from moisture and interference
Sensor data storage
Simplified calibration management
Faster sensor replacement and commissioning
The transmitter can also support analog sensors depending on the selected configuration, providing flexibility when upgrading existing measurement systems.
Designed for Hazardous and Hygienic Applications
The CM42B is developed for demanding process environments where reliability and safety are critical.
With international explosion protection approvals including ATEX, IECEx, C/US and CHN-Ex, the transmitter can be used in hazardous areas when correctly configured.
For hygienic industries such as food & beverage and life sciences, stainless steel housing options are available to support installations requiring high cleaning standards.
Two-wire Design for Simple Installation
The two-wire design reduces wiring requirements and simplifies installation compared with conventional multi-wire transmitter solutions.
Benefits include:
Reduced installation complexity
Lower cabling requirements
Easy integration into existing control systems
Suitable for field and cabinet mounting
The CM42B is available in different housing versions, including field housing and DIN-rail mounting versions for cabinet installation.
Reliable Communication and Process Integration
The CM42B supports standard industrial communication methods for easy connection with automation systems.
Available communication options include:
4…20 mA output
HART communication
Additional current output depending on configuration
HART communication can also be activated later depending on the device version, providing additional flexibility throughout the plant lifecycle.
Easy Operation and Smart Maintenance
The transmitter features an intuitive operating concept designed to simplify commissioning, configuration and daily operation.
Combined with Endress+Hauser digital sensor technology, the CM42B supports efficient measuring point management by helping users:
Reduce commissioning time
Simplify sensor replacement
Improve maintenance planning
