Product Description

The Endress+Hauser Liquiline M CM42B is the upgraded, high-reliability single-channel two-wire analytical transmitter optimized for precise continuous liquid parameter monitoring in standard, hygienic and hazardous industrial environments. As an enhanced iteration of the classic CM42 series, the CM42B delivers improved operational flexibility, safer wireless communication, stronger diagnostic performance and wider certification coverage, making it a cost-effective and future-proof solution for professional process liquid analysis.
This multi-parameter transmitter supports both advanced Memosens digital sensors and conventional analog probes, enabling flexible measurement of pH, ORP, conductivity and dissolved oxygen. Featuring plug-and-play sensor recognition, the CM42B automatically identifies connected sensors and loads matched measurement parameters, which greatly simplifies on-site commissioning, reduces manual configuration errors and shortens project startup time. Users can switch measuring parameters freely according to production demands, achieving versatile monitoring for diverse process water and fluid medium conditions.
Adopting a standard two-wire loop-powered design, the CM42B simplifies field wiring and reduces engineering and maintenance costs. It is equipped with universal 4-20mA analog output with optional HART communication, as well as optional PROFIBUS PA fieldbus interface, supporting seamless integration with mainstream PLC, DCS and industrial control systems. The stable signal output and strong electromagnetic interference resistance ensure long-term consistent measurement performance even in complex industrial electromagnetic environments.
One of the core upgrades of the CM42B is its enhanced wireless operation system. Built-in encrypted Bluetooth module supports stable connection with the E+H SmartBlue App, allowing engineers to remotely view real-time measuring data, adjust parameters, complete calibration and query device logs via mobile devices. The exclusive security encryption mechanism effectively prevents unauthorized access, ensuring safe and convenient off-site operation and improving overall maintenance efficiency.
Equipped with E+H proprietary Heartbeat Technology, the CM42B realizes full-cycle real-time self-diagnosis. The system can actively detect sensor aging, signal abnormality, device fault and working condition anomalies, and trigger timely alarm reminders. This predictive maintenance function avoids unplanned downtime, reduces equipment failure risks and ensures long-term high availability of on-site measuring points.
For harsh industrial application scenarios, the field-mounted housing of the CM42B features IP66/IP67 dustproof and waterproof protection and NEMA 4X rating, adapting to outdoor installation and severe workshop environments. It holds global authoritative certifications including ATEX, IECEx, C/US and CHN-Ex explosion-proof approvals, supporting safe operation in flammable and explosive hazardous areas. Meanwhile, it complies with industrial hygienic standards, fully meeting the strict sanitary requirements of food, beverage and pharmaceutical production processes.
With a user-friendly graphical display and simplified navigator key operation, the CM42B enables intuitive on-site viewing, calibration and parameter setting without complex professional training. Its modular compact structure ensures easy installation and flexible layout, whether for field wall mounting or DIN rail mounting scenarios. Low daily maintenance requirements and excellent long-term operational stability further lower the total operating cost for users.
Widely applicable in municipal and industrial water treatment, chemical processing, power plants, food & beverage, pharmaceutical and life science industries, the Endress+Hauser CM42B serves as a reliable, efficient and intelligent core device for online liquid analytical monitoring in modern process industries.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
