Field of application

Memosens CPS31E is the expert for pH compensation in disinfection processes. It delivers stable measurement results, ensuring safe swimming pool and drinking water. Thanks to Memosens 2.0 digital technology, CPS31E provides the perfect data basis for predictive maintenance, offers easy operation and more process uptime since it can be calibrated in the laboratory and quickly exchanged on site. The sensor resists moisture and its 3 optional junctions make it suitable for minimum conductivity.

Benefits

Reliable: Ceramic junction ensures reliable measurement at low conductivities. For minimum conductivities, 3 junctions are the best choice.
Robust: The optional salt storage provides for extended operating time.
Precise: The sensor shows minimum drift thanks to a very low level of ion depletion in electrolyte.
Memosens 2.0 offers extended storage of calibration and process data. These data are the ideal basis for predictive maintenance and can also be used to develop and provide enhanced IIoT services.
Safe: Non-contact, inductive, digital signal transmission eliminates errors due to moisture.
Cost-efficient: Fast sensor exchange in the field increases process uptime and regeneration extends the sensor lifetime.

Videos

The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.
Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
