Key Features & Advantages

1. Memosens Digital Technology – Reliability Redefined

The groundbreaking Memosens system uses non-contact inductive coupling for power and data transfer. This completely eliminates issues caused by moisture ingress, corrosion, or cable damage at the connection point—a common failure point in traditional analog sensors. The encrypted digital signal ensures absolute data integrity from sensor to transmitter.

2. Predictive Maintenance & Plug-and-Play Operation

Each Memosens sensor stores its complete calibration history, configuration parameters, and operating data directly in its internal memory. This enables true “plug-and-play” replacement: swap a sensor without any on-site recalibration. The technology also provides diagnostic data for predictive maintenance, allowing you to plan servicing before issues arise.

3. Four-Electrode Measurement for Maximum Accuracy

The four-ring (four-electrode) design compensates for polarization effects and cable resistance, providing stable and accurate measurements across an extremely wide range. This makes the CCS51D equally effective in monitoring ultrapure water (low µS/cm) and concentrated solutions (high mS/cm).

4. Robust Design for Harsh Environments

Constructed with chemical-resistant PPS body and durable platinum black electrodes, the CCS51D-AA11BF is built to withstand aggressive media, high temperatures, and rigorous cleaning processes. Its rugged design ensures long service life even in the toughest industrial conditions.

5. Seamless System Integration

The “NC” (No Controller) version is optimized for use with Endress+Hauser’s advanced Liquiline or MyP series transmitters. This modular approach allows for flexible system design and easy integration into existing or new digital process automation architectures.

Why Choose the CCS51D-AA11BF+NC?

This sensor is more than just a measurement device; it’s a cornerstone for smart process management. By delivering drift-free, reliable conductivity data, it helps optimize chemical dosing, ensure product quality, comply with regulations, and protect valuable assets from scaling or corrosion. The reduction in unplanned downtime and maintenance labor offers a rapid return on investment.
