Endress+Hauser CPS91E-BA7BTH2 Precision Chlorine and Conductivity Measurement

The Endress+Hauser CPS91E-BA7BTH2 represents the cutting edge in water quality analysis instrumentation. As a versatile, two-channel sensor, it is expertly engineered for the continuous, reliable monitoring of both chlorine (Cl₂) and conductivity in a wide array of demanding water treatment and process applications. This combination provides plant operators with critical, real-time insights for process control, regulatory compliance, and asset protection.

This robust sensor is particularly vital for industries where water disinfection and purity are paramount, including:

Drinking Water & Wastewater Treatment: Precise chlorine dosing control for effective disinfection while minimizing by-products.

Cooling Towers & Industrial Water Systems: Monitoring biocide treatment and conductivity for blowdown control, ensuring efficiency and preventing corrosion/scale.

Food & Beverage (CIP processes): Verification of cleaning and disinfection effectiveness.

Key Technical Parameters & Features

The CPS91E-BA7BTH2 integrates advanced technology into a durable, user-friendly design:

Dual-Parameter Platform: Simultaneously measures free chlorine (via amperometric method) and conductivity with a single device, reducing installation points and costs.

Advanced Chlorine Measurement: Features a maintenance-friendly, membrane-free RCA® (Ring-Cell Amperometry) sensor for chlorine. This technology offers superior stability, reduced fouling sensitivity, and minimal need for calibration compared to traditional membrane cells.

High-Accuracy Conductivity: Incorporates a high-performance, 4-electrode conductivity cell with TetraCon® 925 technology, providing accurate measurements across a wide range (µS/cm to mS/cm) with excellent temperature compensation.

Robust Construction: Built with durable, chemically resistant materials (PPS, PEEK, stainless steel) suitable for harsh environments. The integrated temperature sensor (Pt1000) ensures precise compensation for both parameters.

Smart Diagnostics & Connectivity: Equipped with Heartbeat Technology for on-demand verification of sensor condition and calibration status. Seamless integration via digital (RS485) or analog (4…20 mA) outputs into Endress+Hauser and third-party control systems.

Core Advantages for Your Operation

Choosing the CPS91E-BA7BTH2 delivers significant operational benefits:

Unmatched Operational Reliability: The membrane-free RCA chlorine sensor drastically cuts maintenance, eliminating membrane replacements and electrolyte refills. Its robust design ensures long-term stability and uptime.

Reduced Total Cost of Ownership: Lower maintenance costs, less reagent consumption (no electrolyte), and reduced calibration frequency translate directly into significant lifecycle savings.

Simplified Process Control & Safety: Continuous, simultaneous measurement of two key parameters provides a comprehensive water quality picture, enabling tighter process control, ensuring disinfection efficacy, and protecting downstream equipment from corrosion or scaling.

Future-Proof Compliance: Delivers the accuracy and data integrity required to meet stringent environmental and public health regulations for water disinfection and discharge.

Endress+Hauser CPS91E-BA7BTH2 is more than just a sensor; it is a intelligent solution for optimized water management. By combining robust hardware with proactive diagnostic intelligence, it sets a new standard for efficiency, reliability, and cost-effectiveness in chlorine and conductivity monitoring.
