Wide Measuring Range with 4-Electrode Technology

Unlike traditional 2-electrode conductivity sensors, the CLS82E uses a 4-electrode measuring principle to provide stable measurement across a very wide conductivity range.

This allows one sensor to monitor different process stages, reducing the need for multiple sensors in hygienic production environments.

Designed for Hygienic Industries

The CLS82E is developed for applications requiring strict hygiene standards, including:

• 
  Pharmaceutical manufacturing
  
• 
  Biotechnology processes
  
• 
  Food and beverage production
  
• 
  Pure water systems
  

The sensor features FDA-compliant materials and hygienic certifications including EHEDG and 3-A depending on configuration.

One Sensor for Multiple Process Steps

The broad measurement range allows the CLS82E to be used for:

• 
  Main process monitoring
  
• 
  Phase separation detection
  
• 
  CIP monitoring
  
• 
  Final rinse monitoring
  
• 
  Ultrafiltration
  
• 
  Fermentation processes
  

This helps simplify inventory and reduce the number of measuring points required.
