The ZW-TB-PR integrated online turbidity sensor adopts the scattered light detection principle. During operation, a incident light beam penetrates the water sample. Turbidity particles within the sample scatter the light beam. The sensor measures the intensity of light scattered at 90 degrees to the incident path. By correlating the measured data with the built-in calibration standard, the system derives the true turbidity value. Post-processing includes linearization algorithm implementation, ensuring the final output is accurate, stable, and ready for system integration.
