Equipped with Memosens 2.0 digital technology, the sensor is resistant to moisture and supports laboratory calibration, enhancing process safety while simplifying operation.

Its advanced storage capability for calibration and process data provides a strong foundation for predictive maintenance. Built for long service life and minimal maintenance, the Memosens CPS11E offers outstanding cost efficiency and dependable performance in demanding applications.

Features

• IIoT ready: 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.

• Low operating costs: Lab calibration and quick sensor exchange in the process result in minimized process downtime and longer sensor lifetime.

• Robust, low maintenance electrode: Long poison diffusion path or optimized ion trap prevent poisoning of the electrode reference. Large, dirt-repellent PTFE junction protects from soiling by the medium.

• Process glass is suitable for the full pH range and pressure-stable up to 17 bar (246.5 psi) absolute. Optional F-glass allows application in media containing hydrofluoric acid such as etching baths in semiconductor production.

• Improved optional salt storage ensures reliable measurement in low conductivity applications such as boiler feed water.

• Maximum process integrity through non-contact, inductive signal transmission.
