1、 Measurement principle:
The sludge concentration sensor is based on the combined infrared absorption scattering method. The infrared light emitted by the light source is scattered by suspended particles in the sample, and finally converted into an electrical signal by a photodetector. After analog and digital signal processing, the sample sludge concentration is obtained.

2、 Main features:

1. The sensor adopts dual beam infrared scattering photometry detection technology, which has good repeatability and stability;

2. The application of ISO7027 standard method (infrared light scattering technology) can eliminate the influence of sample color;

3. Built in self diagnosis function to ensure accurate data;

4. Optional cleaning brush with automatic cleaning function, greatly reducing sensor maintenance;

5. Digital sensors with strong anti-interference ability and long transmission distance;

6. Standard digital signal output, which can be integrated and networked with other devices without a controller;

7. The on-site installation of sensors is convenient and fast, achieving plug and play functionality.

3、 Typical applications:

1. Online monitoring of sludge concentration in various processes of sewage treatment plants;
2. Online monitoring of suspended solids (sludge concentration) in various industrial production processes such as water and wastewater treatment processesMeasure.
