Liquiline CM442 Transmitter
Part number CM442
Two-channel multiparameter transmitter for Memosens digital sensors — pH/ORP, conductivity, oxygen, turbidity — with HART, PROFIBUS, Modbus or EtherNet/IP.
- CE
- UL
- RoHS
- IP67
Overview
The Liquiline CM442 is the field transmitter of Endress+Hauser's Liquiline platform. It accepts up to two Memosens digital sensors of any parameter — pH, ORP, conductivity, dissolved oxygen, turbidity, chlorine — so a single transmitter type can be standardized across a water plant or food process. Memosens sensors are pre-calibrated in the lab and plugged in by hand; the inductive connection is immune to moisture and corrosion. Outputs and fieldbus are modular, and the same operating concept runs on the panel-mounted CM444 and the lab devices.
Key features
- Memosens digital, plug-and-measure sensors with calibration data in the sensor
- Up to 2 sensor channels, any parameter combination
- Up to 8 × 0/4–20 mA outputs, relays, digital inputs
- HART, PROFIBUS DP, Modbus RS485/TCP, EtherNet/IP, PROFINET
- Predictive diagnostics, web server, Heartbeat Technology
Typical applications
- pH / ORP in neutralization and dosing
- Conductivity in water treatment and CIP
- Dissolved oxygen in aeration basins
- Turbidity and chlorine in drinking water

Frequently asked questions
Is the CM442 available from stock, and what is the lead time?
Availability of the Liquiline CM442 Transmitter changes with manufacturer production and distributor stock, so we confirm it per request rather than publishing a number that may be out of date. Send the part number and quantity through the quote form and you will receive stock position and lead time within one business day.
Is the CM442 genuine, and what documentation comes with it?
We supply only genuine Endress+Hauser products sourced from the manufacturer or authorized distribution channels. Each delivery includes the commercial invoice and packing list; a Certificate of Conformance, declaration of conformity and country-of-origin statement are provided on request, and the manufacturer's warranty applies.
Can you ship the CM442 outside Vietnam?
Yes. We quote EXW Hai Phong, FCA/FOB, CIF or DAP and prepare the export documentation. Buyers in Japan, ASEAN, Europe and North America regularly consolidate multi-brand orders with us into one shipment.
What if the CM442 is the wrong variant for my application?
Tell us the application in the notes field. Our engineers check the ordering code against your supply voltage, I/O, communication and environmental requirements and propose the correct variant or a successor part before quoting — at no charge.
