Dual beam colour measurement
Product types
The AF26 is a high precision two-channel colour sensor. It measures the attenuation of light through the process fluid. The AF26 sensor, is specially designed for inline installation and is non-invasive.
Being made up of a detector at 2 wavelengths, this system allows the measurement of the colour despite the presence of bubbles and particles present in the pipe presenting an exclusive advantage to the online operation of the product in all circumstances.
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 color or product concentration in line and during production. By adjusting the optical path, we can detect concentrations in the order of ppm but also in%.
Typical applications:
- Colour measurement (ASTM, APHA, Hazen, ICUMSA, etc.) despite the presence of bubbles.
- Determination of the content of copper, chromate.
- Control of the lowest residual color intensities.
- Determination of iron content (ppm).
- Beer colour determination (EBC). OPL of 1 meter available.
Also available in ATEX version.
