biochemical, food, aquaculture and tap water and other solutions for continuous monitoring of turbidity.

4. Working principle of electrode

The turbidity sensor is composed of a light source, a lens, and a photoelectric element. When the light passes through the liquid sample to be measured, the scattered light at a 90 ° direction with the incident light acts on the photoelectric element and generates an electrical signal that varies with turbidity. The reference signal is sent to the signal processor together. The signal processor uses the integrated circuit as the core to form a stable electronic circuit, which amplifies, filters, calculates, and compensates the signal to make it linearly related to the turbidity of the liquid sample to be measured throughout the measurement range.
