Key Features
-
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 .
Application Scenarios
-
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 .
Note: Specifications are based on manufacturer documentation and industry sources. Verify parameters against the latest technical guides for specific applications .
