Field of application
Memosens CPF81E is the digital, robust solution for harsh environments. It measures reliably and accurately even in abrasive media and at high flow rates. With its integrated assembly, the electrode saves installation space. Thanks to Memosens 2.0 digital technology, CPF81E 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.
Memosens CPF81E is the robust pH sensor for processes in mining industries and treatment of industrial water and wastewater. It monitors:
Flotation
Leaching
Neutralization
Inlet and outlet
With CSA C/US approval for use in hazardous areas, zones 0, 1 and 2.
Benefits
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.
Long time stable: Double junction provides better protection against electrode poisoning ions such as S2- or CN-.
Robust polymer housing protects against mechanical damage.
Optional flat membrane makes the sensor suitable for high flow rates and abrasive media.
Non-contact, inductive signal transmission ensures maximum process safety.
Maximum process uptime and extended sensor lifetime reduce operating costs.
