Endress+Hauser COS41-2F The Ultimate Turbidity Sensor

In industries where liquid clarity is paramount—from drinking water treatment to beverage production—precise and reliable turbidity measurement is non-negotiable. The Endress+Hauser COS41-2F suspended solids and turbidity sensor is engineered to master this critical task. This innovative sensor sets the global standard for in-line turbidity monitoring, delivering exceptional accuracy, robust performance, and minimal maintenance to secure your process quality and operational efficiency.

Technical Specifications & Advanced Design

The COS41-2F is a sophisticated 2-beam, 4-light pulse infrared photometer designed for challenging in-line applications. Its technical prowess is built on a foundation of precision engineering:

Measurement Principles: Utilizes both scattered light (90°) and transmitted light (180°) methods, automatically selecting the optimal principle for each measurement range.

Measurement Ranges: Covers an extensive span from 0.001 to 4000 FNU/NTU (formazin), ensuring applicability from ultrafiltered water to highly turbid process streams.

Accuracy and Reproducibility: Offers outstanding accuracy of ≤ 2% of reading, with reproducibility of ≤ 1% of reading or 0.01 FNU (whichever is greater), guaranteeing consistent, trustworthy data.

Process Conditions: Withstands pressures up to 16 bar and temperatures from 0 to 80°C (32 to 176°F), making it suitable for diverse industrial environments.

Hygienic Design: Features an EHEDG-approved, polished stainless steel housing with CIP/SIP capability (up to 140°C), perfect for food, beverage, and pharmaceutical applications.

Smart Sensor Management: Equipped with heartbit Technology for continuous self-monitoring and PreSens for predictive maintenance alerts.

Key Advantages for Your Process

The Endress+Hauser COS41-2F transcends basic measurement, offering transformative benefits:

Unrivaled Accuracy and Stability: The patented 2-beam/4-light pulse technology compensates for contamination, color, and light source aging, eliminating drift and ensuring stable, long-term accuracy without frequent recalibration.

Lowest Cost of Ownership: Exceptional drift resistance drastically reduces maintenance intervals, calibration effort, and consumable costs. The robust, sensor design eliminates the need for fragile glass cuvettes or sample cells.

Hassle-Free Operation and Integration: The intuitive Memosens digital technology ensures plug-and-play usability, data storage in the sensor head, and seamless, error-free digital communication with compatible transmitters like the CUS71.

Built for the Toughest Conditions: Its hygienic, fully submersible design (IP68) and resistance to fouling make it ideal for direct immersion in tanks, pipelines, or open channels, even under aggressive cleaning regimens.

Enhanced Process Safety and Compliance: Reliable, real-time data enables precise control of filtration, flocculation, and clarification processes, ensuring consistent product quality and helping to meet stringent regulatory standards.

Conclusion

The Endress+Hauser COS41-2F is more than just a turbidity sensor; it is a cornerstone for intelligent process optimization.
