Automatic Cleaning for Optical Sensors
The Endress+Hauser CYR51 is a mechanical cleaning unit developed to maintain reliable operation of optical sensors installed in challenging process conditions.
Optical sensors used in wastewater and process water applications are often exposed to contamination, deposits and biological growth, which can affect measurement accuracy. The CYR51 provides automated mechanical cleaning directly at the measuring point, reducing the need for frequent manual maintenance.
Typical applications include:
Turbidity measurement
Suspended solids monitoring
UV-Vis absorption measurement
Nitrate and SAC monitoring
Mechanical Wiper and Brush Cleaning Principle
The CYR51 uses a mechanical cleaning principle with wiper blades or brushes to remove contamination from the optical surface.
The cleaning process helps:
Maintain stable optical measurement
Reduce sensor fouling
Extend maintenance intervals
Improve long-term measurement reliability
The cleaning unit is designed for continuous operation in environments where sensor surfaces are exposed to particles or deposits.
Compatible with Multiple Optical Sensors
The CYR51 can be integrated with various Endress+Hauser optical sensors.
Compatible sensor applications include:
Turbidity and Suspended Solids Measurement
Compatible with sensors such as:
Turbimax CUS51D
Turbimax CUS52D

Reduced Maintenance and Improved Sensor Availability
Manual cleaning of optical sensors can increase maintenance workload and interrupt measurement.
The CYR51 provides:
Automatic cleaning cycles
Reduced manual intervention
Stable measurement conditions
Improved process availability
This makes it especially suitable for measuring points where regular sensor access is difficult.
Easy Integration into Existing Installations
