The Memosens CPS71D electrode is especially suitable for demanding applications. With its unique fouling-resistant reference system and moisture-proof, waterproof design, it reliably measures heavily contaminated media and corrosive media such as strong acids and alkalis. The CPS71D electrode uses Memosens digital technology, supports extended data storage of calibration and process parameters, and is the perfect basis for predictive maintenance. Sensors can be precalibrated in the laboratory and replaced quickly on site, minimizing production interruptions.
Benefits
The electrode's unique ion trap effectively prevents toxic diffusion in the lead and reference system, enabling measurement of strong acids and alkalis with a long electrode service life.
Optional pressurized reference system for reliable measurement of media prone to clogging, such as dispersions.
Allows inverted electrode installation for flexible mounting.
Inductive cable connection and non-contact signal transmission eliminate the influence of moisture and corrosion, improving process integrity.
Fast electrode replacement on site shortens production downtime and reduces operating costs.
Memosens digital technology supports extended data storage for calibration and process parameters, enabling trend detection and predictive maintenance. It is also the ideal foundation for advancing IIoT technology.
Application areas
Chemical process engineering and process monitoring:
Highly toxic media, e.g. H2S
Rapidly fluctuating pH values
Approved for ATEX, IECEx, CSA C/US, NEPSI, Japan and INMETRO; suitable for use in explosion protection zones 0, 1 and 2.
