Reliable Turbidity Measurement for Water Applications

Water quality monitoring requires accurate and stable turbidity measurement, especially in drinking water production and industrial water treatment.

The CUS52D is designed for drinking water, process water, saline water and industrial utility applications, providing reliable measurement from raw water intake through water treatment and distribution processes.

Laboratory-Level Accuracy in Process Measurement

The sensor uses a nephelometric measurement principle with 90° scattered light according to ISO 7027, allowing accurate turbidity monitoring directly in the process.

This helps reduce the gap between laboratory analysis and online process measurement.

Flexible Installation for Different Processes

The CUS52D supports multiple installation options, including:

• 
  Inline installation
  
• 
  Flow cell installation
  
• 
  Retractable assemblies
  
• 
  Immersion measurement
  

The hygienic stainless steel version can also be mounted directly into pipelines with clamp connections, making it suitable for drinking water applications.

Smart Sensor with Memosens Technology

With Memosens digital technology, the CUS52D stores sensor data and calibration information, helping simplify commissioning, maintenance and predictive sensor management.

Designed for Long-Term Operation

The sensor design focuses on stable measurement performance and reduced maintenance requirements.

Its robust construction, sapphire optical windows and IP68 protection make it suitable for continuous operation in demanding water applications.
