Digital ORP Sensor Memosens CPS42E

Brand: Endress+Hauser Group Services AG

Memosens CPS42E is the high performer for harsh chemical applications, media with low conductivity or considerable organic content. The sensor is designed for fast response especially in applications with fast-changing media. 

Thanks to Memosens 2.0 digital technology, CPS42E combines maximum process integrity with simple operation. It resists moisture and enables lab calibration. It offers extended storage of calibration and process data providing the perfect basis for predictive maintenance.

Media with low conductivities or a high proportion of organic solvents or alcohols and fast changing media:
  • Chemical industry
  • Organic chemicals
  • Power plants, e.g. boiler feed water
  • Laboratory measurements
With ATEX, IECEx, CSA C/US, NEPSI, Japan, INMETRO approvals for use in hazardous areas, zones 0, 1 and 2.
Features
  • 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
  • Resistant to poisoning due to permanent refilling of KCl bridge electrolyte and separate reference lead
  • Perfectly suited for quickly changing media: Combination of liquid KCl electrolyte and ceramic junction enables fast response time
  • Applicable at very low conductivities (> 5 µS/cm) thanks to liquid KCl electrolyte
  • Suitable for cleaning in place (CIP) and sterilization in place (SIP)
  • Maximum process safety through non-contact inductive signal transmission
  • Reduced operating costs due to minimized process downtime and extended sensor lifetime
