The suspended solids sensor is a device used to monitor the concentration of suspended solids in water in real time. Suspended solids sensors usually use optical principles for measurement. Its basic principle is to irradiate the water body by emitting a light source (such as LED), and then use the principle of light scattering or light absorption to measure the concentration of suspended matter. When light passes through a water body, suspended solids scatter or absorb light, and the measuring device can calculate the concentration of suspended solids based on the degree of light scattering or absorption.
The suspended solids sensor can provide real-time monitoring data and keep abreast of the concentration changes of suspended solids in the water body. This helps to quickly identify sources of pollution, unusual events or effects in natural processes. The suspended solids probe has high-precision measurement capabilities and can accurately measure the concentration of suspended solids in water. Suspended solids sensors usually have an anti-pollution and corrosion-resistant design, and can work stably for a long time under various environmental conditions. They are suitable for different types of water bodies such as rivers, lakes, oceans and water treatment facilities. It can be equipped with a self-cleaning wiper version to realize the underwater self-cleaning function. In addition, the suspended solids sensor is equipped with RS485 communication, which has remote monitoring capabilities, and can perform real-time data transmission and monitoring with the central control system through the Internet or wireless communication technology.
