E+H Memosens CPS42E Digital ORP Sensor
Memosens CPS42E
The Endress+Hauser Memosens CPS42E is a high-performance digital ORP sensor designed for continuous oxidation-reduction potential measurement in chemical processing, industrial water, and wastewater treatment. Equipped with Memosens 2.0 digital technology, a poison-resistant reference system, and a dirt-repellent PTFE ring diaphragm, it ensures exceptional measurement stability and contactless data transmission in harsh plant environments.
Advanced Digital ORP Monitoring with Endress+Hauser Memosens CPS42E
The Endress+Hauser Memosens CPS42E is an industrial-grade digital ORP electrode designed for continuous oxidation-reduction potential (redox) measurement in demanding chemical processes, wastewater treatment plants, power generation facilities, and industrial water systems. Optimized to handle media prone to fouling, chemical poisoning, and heavy suspended solids, the CPS42E delivers exceptional accuracy, fast response times, and extended service life through modern digital IIoT integration.
Poison-Resistant Reference System & Dirt-Repellent PTFE Diaphragm
In aggressive industrial and wastewater applications, conventional ORP electrodes often fail due to reference system poisoning (e.g., silver sulfide contamination) or diaphragm clogging caused by suspended solids. The Memosens CPS42E overcomes these challenges through its advanced double-chamber reference system with an ion trap, which protects the reference gel from contamination. Furthermore, its dirt-repellent annular PTFE diaphragm prevents organic buildup and particle adhesion, ensuring stable electrical contact and continuous measurement reliability.
Memosens 2.0 Digital Technology & Contactless Data Transmission
Equipped with cutting-edge Memosens 2.0 technology, the CPS42E converts analog oxidation-reduction potential signals into a digital protocol directly inside the sensor head. Inductive, non-contact signal transmission eliminates corrosion and moisture interference commonly caused by humidity, steam, or washdowns in industrial process environments. The sensor stores calibration history, operating hours, and process load data internally, enabling offline lab calibration and true plug-and-play field replacement without recalibration on the plant floor.
Platinum Ring Measuring Element & High Process Resilience
The high-purity platinum ring measuring element ensures accurate, rapid response for redox reactions and disinfection control. Built to withstand demanding process conditions with high pressure and temperature thresholds, the CPS42E features standard industry thread connections (such as Pg 13.5) for seamless integration into standard process housings, bypass assemblies, and immersion fittings.
