E+H Orbisint CPS12 Analog ORP Sensor
Orbisint CPS12
The Endress+Hauser Orbisint CPS12 is a heavy-duty analog ORP (oxidation-reduction potential) electrode designed for reliable process monitoring in chemical, industrial water, and wastewater treatment. Featuring a dirt-repellent PTFE ring diaphragm and poisoned-resistant reference system, it ensures long-term measurement stability in contaminated and aggressive media.
Reliable Oxidation-Reduction Potential Monitoring with Endress+Hauser Orbisint CPS12
The Endress+Hauser Orbisint CPS12 is an industrial-grade analog ORP electrode designed for continuous oxidation-reduction potential (redox) measurement in demanding chemical processes, wastewater treatment plants, power generation facilities, and industrial water systems. Optimized to handle media prone to fouling, chemical poisoning, and heavy suspended solids, the CPS12 delivers exceptional accuracy, fast response times, and extended service life.
Poison-Resistant Reference System & Dirt-Repellent PTFE Diaphragm
In aggressive industrial and wastewater applications, conventional ORP electrodes often fail due to reference system poisoning (e.g., silver sulfide contamination) or diaphragm clogging caused by suspended solids. The Orbisint CPS12 overcomes these challenges through its advanced double-chamber reference system with an ion trap, which protects the reference gel from contamination. Furthermore, its dirt-repellent annular PTFE diaphragm prevents organic buildup and particle adhesion, ensuring stable electrical contact and continuous measurement reliability.
Key Performance Features & Technical Advantages
-
Contamination-Resistant PTFE Ring: Annular diaphragm design resists clogging and repels dirt in heavily contaminated industrial wastewater and chemical slurries.
-
Double-Chamber Reference System: Integrated ion trap protects against poisoning from sulfides, heavy metals, or organic compounds, extending electrode lifespan.
-
Platinum Ring Measuring Element: High-purity platinum ring ensures accurate, rapid response for redox reactions and disinfection monitoring.
-
High Pressure & Temperature Range: Built to withstand demanding process conditions with high pressure and temperature thresholds.
-
Universal Analog Compatibility: Features standard industry connections (such as G 1½ or Pg 13.5 thread options) and standard analog signal transmission for easy pairing with existing transmitters (e.g., Liquiline CM42).
-
Robust Mechanical Design: Engineered for long-term endurance in harsh chemical environments, reducing sensor replacement frequency and lowering maintenance costs.
Low Maintenance in Tough Industrial Processes
By combining a self-cleaning tendency (via fluid velocity across the PTFE ring) with a poisoned-resistant reference, the Orbisint CPS12 minimizes cleaning intervals. It provides a dependable, cost-effective solution for disinfection control, chemical reaction monitoring, and effluent detoxification processes.
Applications
-
Water & Wastewater Treatment: Disinfection control (chlorination/dechlorination), effluent monitoring, oxidation detoxification, and neutralization basins.
-
Chemical Industry: Chemical manufacturing processes, reaction monitoring, and heavy acid/alkali waste streams.
-
Power Generation: Boiler feed water treatment, cooling tower water management, and flue gas desulfurization (FGD) plants.
-
Pulp & Paper / General Industry: Process water monitoring and industrial effluent treatment facilities.
