Cyclic cleaning
For cyclic cleaning, compressed air is the most suitable option. The cleaning unit is either
supplied or can be retrofitted, and is attached to the sensor head. The following settings are
recommended for the cleaning unit:
Type of fouling
Cleaning interval
Cleaning duration
Severe fouling with rapid buildup of deposits
5 minutes
10 seconds
Low risk of fouling
10 minutes
10 seconds

Signal filter
The sensor is fitted with an internal signal filter function in order to adapt the measurement
flexibly to different measuring requirements. Turbidity measurements based on the principle
of scattered light may have a low signal-to-noise ratio. In addition, disturbances can occur as a
result of air bubbles or fouling, for example.
It is not practicable to even out these disturbances using a high level of damping. This would
counteract the sensitivity of the measured value required in the applications.
