Description
Application
The Memosens CPS76E is a robust solution for simultaneous pH and ORP measurement, designed to excel in challenging environments. Its specialized, contamination-resistant reference system ensures consistent performance even in contaminated or aggressive media and those with low conductivity. With Memosens 2.0 digital technology, the CPS76E offers superior process reliability and user-friendly operation. It is moisture-resistant, supports lab-based calibration, and provides enhanced storage for calibration and process data, forming a strong foundation for predictive maintenance. This sensor is ideal for chemical industry processes and monitoring applications where:
- pH or ORP values change rapidly
- There is a high concentration of electrode poisons like Hâ‚‚S
Certified for use in hazardous areas, the Memosens CPS76E comes with ATEX, IECEx, CSA C/US, NEPSI, Japan, and INMETRO approvals for zones 0, 1, and 2.
Benefits
Memosens 2.0 technology offers expanded data storage capabilities for calibration and process data, enabling better trend analysis and laying a future-proof foundation for predictive maintenance and enhanced IIoT services. It supports simultaneous measurement of pH, ORP, and rH values (in rH mode), delivering a more comprehensive process overview and enabling tighter process control. The sensor’s optional pressurized reference ensures accurate readings in challenging media, such as dispersions. A unique ion trap feature prevents contamination of the electrode junction and reference, significantly extending the sensor's lifespan. It offers flexible installation options, including the ability to be mounted upside-down. With non-contact, inductive signal transmission, the CPS76E maximizes process safety. Reduced operating costs are achieved through minimized process interruptions and an extended sensor lifespan.
