Key Features & Advantages

1. Revolutionary Memosens Digital Technology

The core advantage lies in its non-contact, inductive digital signal transmission. This eliminates moisture-related failures and corrosion at the connector point, ensuring long-term signal integrity and superior reliability in harsh, wet environments.

2. Unmatched Process Safety & Data Integrity

Each sensor stores its unique calibration data, operating history, and parameters directly in its chip. This allows for pre-calibration in the lab, safe and error-free sensor exchange in the field, and full traceability—critical for regulated industries.

3. Robust, Low-Maintenance Design

The DIGMES reference system is gel-based and pressurizable, preventing electrolyte leakage and process contamination. It significantly extends service intervals and sensor lifetime, even in challenging media like wastewater or viscous fluids.

4. Intelligent Diagnostics & Predictive Maintenance

Integrated diagnostics monitor sensor aging, coating, and breakage. This predictive maintenance capability alerts users to potential issues before they cause process downtime, enabling proactive planning and reducing unexpected failures.

5. Exceptional Versatility & Compatibility

Designed for universal use with Endress+Hauser Memosens-enabled transmitters (e.g., Liquiline series), it offers seamless integration. The robust PPS body and temperature-resistant design make it suitable for a vast range of applications from clean-in-place (CIP) to aggressive chemical processes.

Applications

Continuous pH/ORP monitoring in chemical reactors and neutralization tanks

Effluent treatment and discharge control in wastewater plants

Critical control points in pharmaceutical and biotechnology processes

Product quality assurance in food & beverage production

Cooling water and boiler feedwater treatment
