Field of application

Memosens CPS41E features a liquid KCl electrolyte and a ceramic junction making it extremely suitable for harsh chemical applications, fast-changing media and liquids with low conductivity or high organic content. Its integrated Memosens 2.0 digital technology enables extended data storage and lab calibration which results in easier operation and more process uptime and provides the perfect basis for predictive maintenance. The non-contact signal transmission ensures integrity of your process.

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.

Benefits

Memosens 2.0 for perfect support of IIoT, digital transformation and predictive maintenance: It provides enhanced storage of calibration and process data, enabling better trend identification.
Suitable for harsh conditions: Continuous refilling of KCl bridge electrolyte and a separate reference lead prevent poisoning of the electrode.
Application in quickly changing media: Memosens CPS41E offers a fast response time thanks to its liquid KCl electrolyte and ceramic junction.
Liquid KCl electrolyte enables reliable measurement even at very low conductivities (> 0.1 µS/cm).
Suitable for cleaning in place (CIP) and sterilization in place (SIP)
Inductive signal transmission eliminates any interference by moisture, leading to safer processes.
Reduced operating costs: Sensor calibration and regeneration in the lab allows for less process downtime and extends the sensor lifetime.
