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.
