Endress+Hauser CLS54-AMV5022 Precise Sodium Hypochlorite Concentration Measurement

The Endress+Hauser CLS54-AMV5022 is a highly advanced, electrodeless conductivity sensor specifically engineered for the demanding task of measuring concentration in Sodium Hypochlorite (NaClO) solutions. In applications like water disinfection, bleaching, and CIP (Cleaning-in-Place), maintaining precise NaClO concentration is critical for efficacy, safety, and cost-efficiency. The CLS54-AMV5022 excels in this role by providing reliable, maintenance-free, and accurate measurements, even in the harshest chemical environments.

Key Technical Parameters & Introduction

This sensor operates on the principle of electrodeless, or inductive, conductivity. This means it has no direct electrode contact with the aggressive medium, eliminating issues like polarization, coating, and corrosion that plague traditional sensors.

Measurement Principle: Inductive (Electrodeless) Conductivity

Measured Variable: Concentration of Sodium Hypochlorite (typically 0–15 g/l or 0–20%)

Process Temperature Range: Up to 85°C (185°F)

Process Pressure Range: Up to 16 bar (232 psi)

Sensor Material: PFA (Perfluoroalkoxy) housing, providing exceptional chemical resistance.

Output: Integrated temperature measurement (Pt1000) for automatic temperature compensation.

Mounting: Compact, retractable version (AMV) for safe insertion and removal under process conditions.

Core Advantages & Benefits

The CLS54-AMV5022 offers distinct operational and economic benefits:

Zero Maintenance & Long Lifetime: The electrodeless design and robust PFA construction make it immune to fouling and chemical attack, dramatically reducing sensor replacement costs and downtime.

Exceptional Accuracy & Stability: Delivers stable, repeatable concentration readings, ensuring optimal dosing. This prevents under-dosing (which compromises disinfection) and costly over-dosing.

Built for Harsh Chemicals: Specifically designed for aggressive oxidizing agents like NaClO, bromine, and hydrogen peroxide.

Safety and Convenience: The retractable version allows for safe sensor installation, removal, and maintenance without the need to drain pipes or shut down the process.

Seamless Integration: Works perfectly with Endress+Hauser transmitters (like the Liquiline CM44x) for a complete, high-performance measuring loop.

Primary Applications

This sensor is indispensable in industries where NaClO concentration control is paramount:

Water & Wastewater Treatment: Disinfection stages for drinking water, wastewater effluent, and swimming pools.

Chemical Industry: Process control in NaClO production and in various synthesis applications.

Food & Beverage and Pharmaceutical: Concentration monitoring in CIP systems for tank and line disinfection.

Pulp & Paper Industry: Bleaching process control.
