Keeping pH levels stable is a daily challenge for anyone who works with water, chemicals or food. A drift in pH can spoil a batch, cause equipment wear, or even breach safety limits. The Endress+Hauser Digital pH sensor Memosens CPS11E removes guesswork by giving you accurate, long-term pH data and a built-in temperature reading, so you can control the process with confidence.
Endress+Hauser Digital pH sensor Memosens CPS11E with Endress
This sensor is a compact, digital pH electrode designed for stable processes. It connects with an inductive digital head that uses Memosens 2.0 technology, making wiring simple and reliable. If you have struggled with noisy analog signals or frequent recalibration, this device gives you a clean, ready-to-use signal that stays accurate for months. The Endress brand ensures you get a sensor built for harsh environments and certified for hazardous zones.
Benefits
-
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.
Field of Application
Memosens CPS11E is the digital all-rounder for stable processes. It measures reliably even in extreme pH ranges or hazardous areas. Thanks to Memosens 2.0 digital technology, the pH sensor resists moisture and enables lab calibration, increasing process safety and simplifying operation. Its extended storage of calibration and process data provides the perfect basis for predictive maintenance. Designed for a long operating life and low maintenance, Memosens CPS11E offers you best value for money.
