ABB UviTec™ Water Quality Monitoring
See all products
ABB conductivity sensors provide industry leading precision and durability for continuous water analysis, offering advanced contacting and toroidal technologies to optimize process control and equipment protection in the most demanding industrial environments.
ABB’s conductivity offering is engineered to provide stability and repeatability across a wide range of industrial applications. By selecting the correct sensor technology, facilities can ensure precise control over water purity, chemical concentration, and process efficiency.
The AC200 series is the definitive solution for low-conductivity and high-purity water applications. These sensors utilize direct electrode contact to achieve extreme sensitivity.
Applications: Boiler feed water, demineralization plants, semiconductor manufacturing, and power plant steam cycles.
Key Features: Available with stainless steel or graphite electrodes and a variety of cell constants to match your specific range requirements.
Durability: Designed to withstand high pressures and temperatures, ensuring long-term reliability in sensitive environments.
For aggressive or “dirty” process fluids, the TB400 series utilizes inductive magnetic technology. Because no electrodes are in contact with the process fluid, these sensors are virtually immune to the issues that plague standard sensors.
Applications: Chemical processing, pulp and paper slurries, wastewater effluent, and Clean-in-Place (CIP) concentration monitoring.
Key Features: Eliminates electrode polarization and resists coating or fouling.
Material Options: Constructed from chemically resistant materials such as PEEK, PVDF, and Teflon to survive the most corrosive environments.
ABB provides hygienic conductivity sensors specifically designed for the food, beverage, and pharmaceutical sectors. These models feature 3-A sanitary certifications and are built to withstand the thermal shocks of frequent sterilization cycles.
ABB conductivity sensors are built to integrate seamlessly into modern industrial control architectures. When paired with ABB transmitters, they offer a complete analytical loop with advanced diagnostic capabilities.
Smart Communication: Full support for HART, PROFIBUS, and FOUNDATION Fieldbus protocols allows for remote monitoring and predictive maintenance.
Temperature Compensation: Integrated Pt100 or Pt1000 RTDs provide accurate, real-time temperature compensation, which is critical for maintaining measurement integrity as process temperatures fluctuate.
Rugged Construction: Sensors are available with various mounting options, including submersible, flow-through, and retractable (hot-tap) configurations to suit any installation requirement.
