Field of application
Memosens CPS72E is the digital specialist for demanding processes. Its unique, contamination-resistant reference guarantees stable measurement in poisoning media but also in media with low conductivity. Thanks to Memosens 2.0 digital technology, CPS72E combines maximum process integrity with simple operation. It resists moisture, enables lab calibration and offers extended storage of calibration and process data providing the perfect basis for predictive maintenance and IIoT services.
Processes in chemical industry and monitoring of processes with:Quickly changing ORP valuesHigh proportion of electrode poisons such as H2S With ATEX, IECEx, CSA C/US, NEPSI, Japan, INMETRO approvals for use in hazardous areas, zones 0, 1 and 2.
Benefits
Memosens 2.0 offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services. The sensor resists strong acids and bases and high organic loads. Its unique ion trap prevents poisoning of the junction and reference, ensuring a long sensor lifetime.Non-contact, inductive signal transmission maximizes process safety. Reduced process downtime and extended sensor lifetime minimize operating costs.
