Key Features & Advantages

Unmatched Data Integrity & Process Safety

Memosens technology eliminates all electrical contacts in the measuring point. This prevents corrosion, moisture ingress, and signal drift caused by cable damage, guaranteeing 100% data integrity. The digital protocol ensures the measured value is transmitted perfectly from the sensor to the transmitter.

Predictive Maintenance & Reduced Downtime

The sensor stores its entire calibration history, manufacturer data, and operating hours digitally on an embedded chip. This enables condition monitoring, informs you when service is due, and allows for pre-calibration in the lab. Swapping a pre-calibrated sensor takes seconds, minimizing process interruption.

Exceptional Accuracy for Low Conductivity

With a cell constant of k=0.1 cm⁻¹ and high-grade platinum electrodes, the CCS50D delivers outstanding accuracy in low-conductivity media, such as ultrapure water (UPW) or Water for Injection (WFI), which is critical for compliance in pharmaceutical and microelectronics production.

Robust & Hygienic Design

The sensor body made of chemically resistant PPSU withstands aggressive cleaning agents and harsh process conditions. Its smooth surfaces and suitable materials also make it an excellent choice for hygienic and sanitary applications.

Future-Proof Investment & Easy Integration

Memosens is the standardized digital platform from Endress+Hauser. Investing in the CCS50D ensures compatibility with a wide range of transmitters (like the Liquiline CM44x) and seamless integration into digital plant ecosystems (IIoT, Industry 4.0), protecting your investment for the long term.

Why Choose the Endress+Hauser CCS50D Sensor?

The CCS50D-AA11BF+NC is not just a sensor; it's a cornerstone for intelligent process analytics. It solves the classic problems of analog conductivity measurement—corrosion, calibration drift, and unexpected failures—by digitizing the sensor itself. This results in higher plant availability, lower total cost of ownership, and guaranteed data quality for regulatory compliance.

Ideal for: Monitoring ultrapure water, controlling dilution processes, clean-in-place (CIP) rinse control, concentration measurement, and leakage detection in heat exchangers.
