Accuracy: Excellent long-term stability with minimal drift, providing reproducible results.

Process Connection: Immersion version with adjustable mounting (A2 version), suitable for installation in tanks, basins, or channels.

Materials: High-quality stainless steel (316L) housing and sapphire glass window for exceptional corrosion and abrasion resistance.

Communications: Integrated analog (4...20 mA) and digital outputs (HART, Modbus RS485). Seamless integration into control systems via Memosens technology.

Certifications: Complies with international standards, including IEC/EN 61326, and holds approvals for use in hazardous areas (ATEX, IECEx).

Operating Conditions: Temperature range: -20 to 60 °C; Pressure up to 6 bar.

Unmatched Advantages for Your Process

1. Unrivaled Measurement Reliability

The patented 4-beam alternating light principle compensates for window fouling, color, and aging of the light source. This drastically reduces maintenance needs and provides unmatched measurement stability, even in the harshest environments.

2. Future-Proof Digital Intelligence

Equipped with Memosens 2.0 digital technology, the COS61-A2F0 enables predictive maintenance, secure data storage, and error-free data transmission. Sensors can be pre-calibrated in the lab, minimizing process downtime.

3. Exceptional Ease of Use & Maintenance

With no moving parts and a clean, simple design, the sensor is easy to install and service. The "Clean in Place" (CIP) capability and lens cleaning systems (optional) further enhance operational efficiency.

4. Versatility for Diverse Applications

From monitoring filter effluent and drinking water clarity to measuring sludge blanket levels in clarifiers and digester feed concentration, the COS61-A2F0 is a single, adaptable solution for multiple critical control points.

5. Reduced Total Cost of Ownership

High accuracy minimizes chemical dosing costs. Low maintenance requirements and long service intervals, supported by robust construction and self-diagnostics, lead to significant operational savings over the sensor's lifecycle.

Ideal For:

Influent/Effluent Monitoring

Sludge Blanket Detection

Flocculation & Precipitation Control

Filter Break-through Monitoring

Digester Feed Concentration Control
