E+H Memosens CPS77E Digital ISFET pH Sensor
Memosens CPS77E
The Endress+Hauser Memosens CPS77E is a shatterproof digital ISFET pH sensor designed for hygienic applications in the food, beverage, and life sciences industries where glass contamination must be strictly prevented. Operating on inductive Memosens 2.0 digital technology, it provides fast, stable pH measurements and withstands harsh Clean-In-Place (CIP) and Sterilization-In-Place (SIP) cycles.
Hygienic Glass-Free pH Measurement with Endress+Hauser Memosens CPS77E
The Endress+Hauser Memosens CPS77E is a premier digital ISFET (Ion-Selective Field-Effect Transistor) pH sensor engineered specifically for hygienic processes in the food, beverage, pharmaceutical, and biotechnology sectors. In processes where traditional glass pH electrodes pose a risk of glass breakage and batch contamination, the CPS77E provides a 100% glass-free, shatterproof alternative that maintains strict compliance with sanitary production guidelines.
Advanced ISFET Chip & Shatterproof PEEK Design
Unlike conventional pH glass bulbs, the Memosens CPS77E utilizes an integrated semiconductor ISFET chip embedded in a biocompatible PEEK (Polyether ether ketone) shaft. The ISFET chip directly measures hydrogen ion activity at the gate surface, yielding exceptionally fast response times even at low temperatures. Its completely non-glass, robust physical construction prevents physical breakage during installation, manual handling, or intense vessel agitator operation, safeguarding product integrity across high-value hygienic batches.
Memosens 2.0 Digital Technology & Contactless Signal Transmission
Equipped with cutting-edge Memosens 2.0 technology, the CPS77E converts analog pH signals into a digital protocol directly inside the sensor head. Inductive, non-contact signal transmission eliminates corrosion and moisture interference commonly caused by humidity, steam, or washdowns in hygienic processing environments. The sensor stores calibration history, operating hours, and process load data internally, enabling offline lab calibration and true plug-and-play field replacement without recalibration on the plant floor.
