Field of application
Memosens CPS91E is equipped with Memosens 2.0 digital technology, offering enhanced data storage for predictive maintenance and IIoT. The sensor features an open aperture that prevents fouling and ensures the most reliable measurement in fibrous media or media with a high content of suspended solids such as dispersions, precipitations or emulsions. Memosens CPS91E is completely resistant to moisture and can be pre-calibrated in the lab which facilitates operation and improves process integrity.
Chemical processes
Pulp and paper industry
Contaminated media and suspended solids
- Dispersions
- Precipitations
- Emulsions
With ATEX, IECEx, CSA C/US, NEPSI, Japan, INMETRO approvals for use in hazardous areas, zones 0, 1 and 2.
Benefits
Reliable measurement in heavily soiled media: Open aperture cannot be blocked by fibres or suspended solids.
-
Not affected by fluctuations in pressure and temperature: Thanks to open aperture no diffusion potential can build up at the junction.
-
Stabilized gel filling allows for low maintenance and a long sensor lifetime.
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.
Non-contact, inductive signal transmission eliminates disturbances caused by moisture or corrosion, ensuring highest process safety.
-
Lab calibration and quick sensor exchange in the process maximize process uptime and reduce operating costs.
