The AF56-N is a high precision turbidity sensor. It measures the attenuation of light through the process fluid. The AF56-N sensor is specially designed for inline installation and is non-invasive.
Its modular structure offers maximum flexibility for direct connection to the production line, without influencing the measurement accuracy. The fluid is crossed by a focused and constant light beam. This measurement of the intensity of the light transmitted in relation to the light emitted allows the monitoring of variations in turbidity in line and during production.
By adjusting the optical path, it can detect concentrations in the order of ppm but also in %. The Model AF56-N sensor uses near infrared (NIR) light from 730 to 970 nm, which makes the measurement independent of color changes in the process medium.
Typical applications: Control of settling, Filter control, Phase separation, Control of the concentration of yeast, biomass.
