Turbimax CUS51D
Sensor for turbidity and solids content
Installation and immersion sensor for low, middle and high turbidity and
solids concentrations
TI00461C/07/EN/14.12
71159923
Application
Turbimax CUS51D is a sensor for all applications of wastewater
treatment.
• Turbidity measurement in the outlet
• Suspended solids in the activated sludge basin and in the
recirculation
• Suspended solids in the sludge treatment
• Filterable solids in the outlet
Your benefits
• All sensor principles (90°, 135° and four-beam pulsed light)
are included in the sensor head and allow optimal adaption to
the measurement task.
• The sensor is factory-calibrated (basis formazine). All
selectable applications (e.g. activated sludge) are precalibrated
and allow quick and easy commissioning.
• Standardized communication (Memosens technology) allows
"plug and play".
• Intelligent sensor - all characteristics and calibration values
are stored in the sensor.
• Calibrations provided by the customer with up to 5 points -
realizable in lab or on site.

Page 2: Function And System Design
Turbimax CUS51D Function and system design Measuring principle For turbidity measurement a light beam is sent through the medium and is diverted from its original direction by optically denser particles, e.g. solid matter particles. This process is also called scattering. - Page 3 Turbimax CUS51D Sensor design The turbidity sensor CUS51D is equipped with two independing sensor units that are arranged in parallel. The application-specific analysis of both signals results in stable measured values. a0012966 Arrangement of the light souces and the light receivers Light sources 1 and 2 135°...
- Page 4 Turbimax CUS51D 90° scattered light method The measurement uses a wavelength of 860 nm like described in ISO 7027 / EN 27027. The transmitted light beam is scattered by the solid matter particles in the medium. The scattered beams are detected by scattered light receivers which are arranged at an angle of 90 °...
