Field of application
Turbimax CUS50D is a smart sensor that allows unattended operation in a wide range of industrial wastewater and process applications. Its absorption principle enables single-point-calibration. Choose from different integrated analytical models to adapt the sensor to your specific application. With Memosens digital technology, Turbimax CUS50D combines maximum process and data integrity with simple operation. It resists corrosion and enables lab calibration.
Turbimax CUS50D measures turbidity, suspended solids and absorption in:
- Industrial wastewater and utilities: 
 - Measurement of the solids content in process and wastewater sludge
 - Flocculent dosing via absorption measurement
 - Concentration measurement of milk products in wastewater
- Process media: 
 Concentration measurement of process media, e.g. titanium dioxide
- Highly absorptive media: 
 Concentration measurement in very dark media, e.g. in the 4th cleaning step of sewage treatment plants
Benefits
-  High level of measurement accuracy and repeatability for stable measurements – in the middle and high turbidity measuring range 
-  High chemical resistance, low maintenance required: Sensor head consists completely of a dirt-repellent Teflon derivative. 
-  The robust plastic version of the sensor is designed for the use in corrosive media or saltwater. 
-  Fast and easy commissioning: Sensor comes pre-calibrated, includes various application models and can easily be adjusted via single-point-calibration. 
-  Automatic sludge model independently selects the optimum signal path for every sludge type. 
-  Perfect process adaption: Fast sensor positioning with a large variety of Endress+Hauser assemblies.
