COS22E: Hygienic Oxygen Measurement Excellence

The Endress+Hauser Memosens COS22E represents the pinnacle of hygienic oxygen measurement, fully compliant with FDA and USP regulations, making it ideal for sensitive applications in life sciences and food & beverages. This sensor is designed for low maintenance, ensuring long-term stability even through frequent sterilization cycles, a critical factor in sterile environments. The trace version further safeguards products, processes, and plant equipment by minimizing oxygen’s detrimental influences. Leveraging the advanced Memosens 2.0 digital technology, the COS22E offers expanded storage for calibration and process data, laying a perfect foundation for predictive maintenance strategies and highly efficient operations, ensuring product safety and quality.

Life Sciences: Precision in Fermentation Control

In the life sciences and biotechnology sectors, precise control of critical parameters is essential for successful fermentation processes. The Memosens COS22E is expertly designed for this purpose, enabling accurate measurement of oxygen levels within bioreactors and fermentation tanks. Its compliance with FDA and USP standards guarantees the safety and integrity of sensitive biological products. The sensor’s ability to withstand frequent sterilization cycles ensures reliable and continuous operation, while the Memosens 2.0 technology provides the data needed for effective process optimization and predictive maintenance, contributing to higher yields and consistent product quality in enzyme production and culture preparations.

Food & Beverages: Ensuring Product Integrity

For the food and beverage industry, maintaining product quality and safety is paramount. The Memosens COS22E plays a vital role by ensuring residual oxygen levels are precisely controlled during various processing stages. Its hygienic design and regulatory compliance (FDA, USP) make it suitable for direct contact with food products, preventing contamination and ensuring consumer safety. The sensor’s long-term stability and low maintenance requirements, even with frequent cleaning and sterilization, contribute to increased plant availability and reduced operational costs. Accurate oxygen measurement is key to preserving flavor, texture, and shelf-life in a wide array of food and beverage products.

Water Treatment: Safeguarding Boiler Feedwater

In water treatment applications, particularly for boiler feedwater, managing oxygen content is crucial to prevent corrosion and ensure the longevity of equipment. The Memosens COS22E provides highly accurate amperometric oxygen measurement, enabling precise control and monitoring of oxygen levels in these critical systems. Its ability to maintain stability through frequent sterilization cycles, coupled with its robust design, makes it ideal for the harsh conditions often found in boiler systems. The Memosens 2.0 technology further enhances operational efficiency by providing detailed process data for effective trend analysis and predictive maintenance, ensuring system integrity.

Inertization Processes: Protecting Sensitive Products

Inertization processes are vital in many industries to protect sensitive materials or products from oxidation or degradation caused by atmospheric oxygen. The Memosens COS22E, especially its trace version, is perfectly suited for monitoring and controlling these processes. It ensures that oxygen levels are reduced to the required minimal levels, thereby safeguarding products and plant equipment. The sensor’s accuracy and reliability, combined with its ease of maintenance and digital data management capabilities, provide the control necessary for successful inertization, protecting valuable products and maintaining their quality and integrity throughout storage or processing.

Hazardous Area Suitability: Safety and Compliance

With international explosion-protection approvals, the Memosens COS22E digital sensor is a safe and compliant choice for use in hazardous areas. This capability expands its application range significantly, allowing for precise oxygen measurement in environments where flammable gases or dusts may be present. The sensor’s design incorporates robust materials and secure connections, ensuring operational safety even under challenging conditions. This adherence to strict safety standards, alongside its hygienic compliance and advanced measurement technology, makes the COS22E a versatile and dependable solution across a broad spectrum of industrial and sensitive applications.

IIoT Ready: Future-Proofing Operations with Data

The Memosens COS22E is engineered with the future of industrial operations in mind, being “IIoT ready” thanks to its Memosens 2.0 technology. This digital platform allows for the extended storage of vital calibration and process data, creating a solid foundation for identifying trends, optimizing processes, and implementing predictive maintenance strategies. By providing richer data insights, the COS22E enables enhanced IIoT services, leading to increased plant availability and more efficient, proactive management of operations. This forward-thinking approach ensures that facilities can leverage the full potential of connected industrial systems.
