Communication: Memosens 2.0 digital protocol. Ensures contactless, inductive data transmission for perfect galvanic isolation.

Process Connection: DIN 1" thread, suitable for standard immersion and flow assemblies.

Sensor Body Material: PPSU (Polyphenylsulfone), offering excellent chemical resistance and mechanical stability.

Measuring Element: High-temperature pH glass, resistant to thermal shock and harsh chemical environments.

Reference System: Gel electrolyte with PTFE (Teflon) diaphragm. Resists fouling and poisoning, ideal for processes with heavy metals, sulphides, or proteins.

Temperature Range: Up to 130 °C (266 °F) and up to 10 bar (145 psi), accommodating high-pressure sterilization and hot process media.

Integrated Data Storage: Memosens chip stores calibration data, sensor lifetime, process parameters, and maintenance history.

Core Advantages for Your Process

1. Unmatched Reliability & Uptime

The hermetically sealed Memosens digital connection eliminates moisture ingress and corrosion at the plug point—a leading cause of sensor failure. The rugged PTFE reference diaphragm dramatically extends operational life in fouling applications, reducing unplanned downtime and maintenance costs.

2. Predictive Maintenance & Process Safety

Digital intelligence is the key differentiator. The sensor continuously logs its operational life and load profile. This enables predictive maintenance—you are alerted to necessary service before measurement drift occurs. Pre-calibration in the safe lab environment eliminates on-site calibration errors, ensuring first-time-right installation and enhanced process safety.

3. Reduced Total Cost of Ownership (TCO)

While a premium instrument, the CPS97E delivers significant long-term savings. Extended calibration intervals, reduced sensor failures, and efficient lab-based management lower spare parts inventory, labor costs, and process risks.

4. Optimal for Harsh Applications

The combination of PPSU body, high-temperature glass, and a fouling-resistant PTFE diaphragm makes the CPS97E-AA8BHH2 the ideal choice for demanding sectors:

Chemical Processing: Aggressive acids, alkalis, and solvent-containing media.

Pharmaceutical & Biotechnology: CIP/SIP (Cleaning/Sterilization-in-Place) processes up to 130°C.

Wastewater Treatment: Sludge, digester, and industrial effluent with high fouling potential.

Power Industry: Scrubber control and boiler feedwater monitoring.

Conclusion

The Endress+Hauser CPS97E-AA8BHH2 is more than just a sensor; it is a foundational component for a robust, data-driven process analytics strategy. By delivering lab-accurate measurements in the field with unparalleled reliability, it empowers industries to optimize product quality, ensure regulatory compliance, and maximize operational efficiency.
