Endress+Hauser CPF81E Digital pH Sensor with IP68 Rating Robust PPS Housing and Dual-Chamber Reference System

The Endress+Hauser CPF81E is a digital pH sensor designed for demanding industrial environments such as mining, wastewater treatment, and chemical processes. It incorporates Memosens 2.0 digital technology, enabling contactless signal transmission, laboratory pre-calibration, and embedded data storage for predictive maintenance. With a robust PPS housing, dual-chamber reference system, and IP68 rating, the CPF81E ensures long-term stability in corrosive, high-flow, or particle-laden media while minimizing operational downtime.

• Digital Reliability with Memosens 2.0: The sensor uses inductive signal transmission to eliminate moisture corrosion and cable faults. It stores calibration data and process parameters directly in the electrode, enabling plug-and-play replacement and trend analysis for predictive maintenance.
• Robust Design for Harsh Conditions: The PPS housing and PTFE planar diaphragm resist abrasion, chemical exposure, and high-flow media (e.g., mining slurries or fibrous wastewater). The dual-chamber reference system reduces ion poisoning (e.g., from S²⁻ or CN⁻).
• Pre-Maintenance Capabilities: Historical data tracking allows users to monitor sensor health and plan maintenance proactively. Laboratory calibration ensures accuracy before field deployment, cutting downtime by up to 50%.
• Easy Integration and Installation: The compact design includes a built-in mounting bracket for immersion or flow-through setups. Compatibility with Endress+Hauser transmitters (e.g., Liquiline series) simplifies integration into automated systems.
• Explosion-Proof Safety: Optional ATEX/FM certifications enable use in hazardous areas, such as chemical plants or mining facilities, without external isolators.

• Mining and Metallurgy: Monitors pH in flotation, leaching, and neutralization processes, withstanding abrasive slurries and corrosive ions.
• Wastewater Treatment: Treated water inlet/outlet pH control in municipal or industrial plants, resistant to clogging from fibers or solids.
• Chemical and Process Industries: Suitable for high-pH or acidic media in chemical reactors, pipelines, and effluent streams, ensuring precise measurement under variable temperatures and pressures.
• Water Management: Continuous monitoring in drinking water systems or surface water bodies, with IP68 rating for submerged installations.
