Digital pH Sensor Memosens CPS11E

Application

The Memosens CPS11E is a versatile digital sensor designed for stable processes, delivering reliable measurements even in extreme pH ranges or hazardous environments. Equipped with Memosens 2.0 digital technology, this sensor is resistant to moisture and allows for lab calibration, enhancing both process safety and operational efficiency. Its extended capacity for storing calibration and process data also supports predictive maintenance, making it an ideal choice for long-term, low-maintenance applications. It excels in long-term process monitoring and limit monitoring where process conditions remain stable, such as in:

• The chemical industry
• Pulp & paper production
• Power plants (e.g., flue gas washers, boiler feed water)
• Incineration facilities

In water and wastewater treatment, it is suitable for:

• Drinking water
• Cooling water
• Well water
• Wastewater treatment facilities

With approvals like ATEX, IECEx, CSA C/US, NEPSI, Japan, and INMETRO, the sensor is certified for use in hazardous zones 0, 1, and 2.

Benefits

• IIoT Ready: Memosens 2.0 technology extends the storage of calibration and process data, facilitating better trend analysis and laying a solid foundation for predictive maintenance and advanced IIoT services.
• Reduced Operating Costs: The ability to calibrate the sensor in the lab and swiftly replace it in the process minimizes downtime and extends sensor lifespan.
• Durable, Low-Maintenance Electrode: The sensor features a long poison diffusion path or optimized ion trap to prevent electrode poisoning. Its large, dirt-repellent PTFE junction ensures protection from medium contamination.
• Versatile Process Glass: Designed to operate across the full pH range, the sensor is pressure-stable up to 17 bar (246.5 psi). An optional F-glass version allows use in hydrofluoric acid-containing media, such as etching baths in semiconductor production.
• Enhanced Salt Storage: An improved optional salt reservoir ensures accurate measurements in low-conductivity environments, such as boiler feed water.
• Maximum Process Integrity: The non-contact, inductive signal transmission ensures the highest level of process integrity.
