Endress+Hauser Orbipac CPF82D-7PA11 Compact Digital ORP Sensor
The Endress+Hauser Orbipac CPF82D-7PA11 is a heavy-duty digital Memosens ORP (Redox) sensor designed for reliable performance in harsh process environments, industrial wastewater, and mining operations. Constructed with a robust Polyphenylene Sulfide (PPS) housing and a NPT ¾» threaded connection, this compact electrode integrates a platinum measuring element and a double-chamber reference system with a patented potassium nitrate ($\text{KNO}_3$) electrolyte bridge to resist aggressive electrode poisons.

Commercial Key Benefits & Applications
-
Poison-Resistant Reference Design: Second electrolyte bridge protects against electrode-poisoning ions (such as sulfides $\text{S}^{2-}$ and cyanides $\text{CN}^-$), ensuring continuous measurement stability in flotation, leaching, and neutralization processes.
-
Low Maintenance Requirements: Dirt-repellent PTFE ring diaphragm minimizes fouling and clogging, significantly reducing downtime and cleaning cycles.
-
Memosens Data Integrity: Contactless inductive transmission resists cable moisture and corrosion while internal sensor memory enables off-site calibration and predictive diagnostics.
