Field of application
The range of application comprises control, feedback control and monitoring.
CarboVis 701 IQ TS
CarboVis 705 IQ TS
The ultrasound cleaning system ensures low maintenance and long-term reli-
able measurement operation.
The ultrasound source integrated in the sensor excites the measurement
windows to produce vibrations in the ultrasound range. The
movement of the surface as a result of this prevents the growth of
pollution in almost all cases and, thus, ensures reliable measured
values during continuous operation.
The sensor is designed to be equipped with an additional compressed air-driven
cleaning system, which supports the ultrasound cleaning system as necessary.

Measuring principle of the sensor CarboVis 70x IQ TS
The sensor operates according to the measuring principle of UV-VIS- spectrom-
etry.
Any substance present in a measuring solution attenuates a light beam that
penetrates the measuring solution. The attenuation (absorbance) of the light
beam is measured for individual wavelengths.The wavelength dependent distri-
bution produces the absorbance spectrum.
The wavelength range where an absorbance occurs is characteristic of the
substance.The extent of the absorbance depends on the amount of the
substance.
The influence of typical interference matrix variants occurring at municipal waste
water treatment plants can be eliminated by including the entire absorbance
spectrum.
With this measuring principle, measuring does not take place continuously but
at intervals.
